-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: MozillaFirefox,seamonkey Announcement ID: SUSE-SA:2008:058 Date: Fri, 19 Dec 2008 12:00:00 +0000 Affected Products: openSUSE 10.3 openSUSE 11.0 openSUSE 11.1 Vulnerability Type: remote code execution Severity (1-10): 8 SUSE Default Package: yes Cross-References: CVE-2008-5500, CVE-2008-5501, CVE-2008-5502 CVE-2008-5503, CVE-2008-5505, CVE-2008-5506 CVE-2008-5507, CVE-2008-5508, CVE-2008-5510 CVE-2008-5511, CVE-2008-5512, CVE-2008-5513 MFSA 2008-60, MFSA 2008-61, MFSA 2008-63 MFSA 2008-64, MFSA 2008-65, MFSA 2008-66 MFSA 2008-67, MFSA 2008-68, MFSA 2008-69 Content of This Advisory: 1) Security Vulnerability Resolved: Mozilla security problems Problem Description 2) Solution or Work-Around 3) Special Instructions and Notes 4) Package Location and Checksums 5) Pending Vulnerabilities, Solutions, and Work-Arounds: See SUSE Security Summary Report 6) Authenticity Verification and Additional Information ______________________________________________________________________________ 1) Problem Description and Brief Discussion The Mozilla Firefox browser was updated to version 3.0.5, fixing various security issues and stability problems. The Mozilla Seamonkey browser was updated to version 1.1.14, also fixing various security issues and stability problems. The other Mozilla browsers and suites are still being prepared and will be released when they have passed QA. The following security issues were fixed: MFSA 2008-69 / CVE-2008-5513: Mozilla security researcher moz_bug_r_a4 reported vulnerabilities in the session-restore feature by which content could be injected into an incorrect document storage location, including storage locations for other domains. An attacker could utilize these issues to violate the browser's same-origin policy and perform an XSS attack while SessionStore data is being restored. moz_bug_r_a4 also reported that one variant could be used by an attacker to run arbitrary JavaScript with chrome privileges. MFSA 2008-68 / CVE-2008-5512 / CVE-2008-5511: Mozilla security researcher moz_bug_r_a4 reported that an XBL binding, when attached to an unloaded document, can be used to violate the same-origin policy and execute arbitrary JavaScript within the context of a different website. moz_bug_r_a4 also reported two vulnerabilities by which page content can pollute XPCNativeWrappers and run arbitrary JavaScript with chrome privileges. Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Workaround Disable JavaScript until a version containing these fixes can be installed. MFSA 2008-67 / CVE-2008-5510: Kojima Hajime reported that unlike literal null characters which were handled correctly, the escaped form '\0' was ignored by the CSS parser and treated as if it was not present in the CSS input string. This issue could potentially be used to bypass script sanitation routines in web applications. The severity of this issue was determined to be low. MFSA 2008-66 / CVE-2008-5508: Perl developer Chip Salzenberg reported that certain control characters, when placed at the beginning of a URL, would lead to incorrect parsing resulting in a malformed URL being output by the parser. IBM researchers Justin Schuh, Tom Cross, and Peter William also reported a related symptom as part of their research that resulted in MFSA 2008-37. There was no direct security impact from this issue and its effect was limited to the improper rendering of hyperlinks containing specific characters. The severity of this issue was determined to be low. MFSA 2008-65 / CVE-2008-5507: Google security researcher Chris Evans reported that a website could access a limited amount of data from a different domain by loading a same-domain JavaScript URL which redirects to an off-domain target resource containing data which is not parsable as JavaScript. Upon attempting to load the data as JavaScript a syntax error is generated that can reveal some of the file context via the window.onerror DOM API. This issue could be used by a malicious website to steal private data from users who are authenticated on the redirected website. How much data could be at risk would depend on the format of the data and how the JavaScript parser attempts to interpret it. For most files the amount of data that can be recovered would be limited to the first word or two. Some data files might allow deeper probing with repeated loads. Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Workaround Disable JavaScript until a version containing these fixes can be installed. MFSA 2008-64 / CVE-2008-5506: Marius Schilder of Google Security reported that when a XMLHttpRequest is made to a same-origin resource which 302 redirects to a resource in a different domain, the response from the cross-domain resource is readable by the site issuing the XHR. Cookies marked HttpOnly were not readable, but other potentially sensitive data could be revealed in the XHR response including URL parameters and content in the response body. Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Workaround Disable JavaScript until a version containing these fixes can be installed. MFSA 2008-63 / CVE-2008-5505: Security researcher Hish reported that the persist attribute in XUL elements can be used to store cookie-like information on a user's computer which could later be read by a website. This creates a privacy issue for users who have a non-standard cookie preference and wish to prevent sites from setting cookies on their machine. Even with cookies turned off, this issue could be used by a website to write persistent data in a user's browser and track the user across browsing sessions. Additionally, this issue could allow a website to bypass the limits normally placed on cookie size and number. MFSA 2008-60 / CVE-2008-5502 / CVE-2008-5501 / CVE-2008-5500: Mozilla developers identified and fixed several stability bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these crashes showed evidence of memory corruption under certain circumstances and we presume that with enough effort at least some of these could be exploited to run arbitrary code. Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Without further investigation we cannot rule out the possibility that for some of these an attacker might be able to prepare memory for exploitation through some means other than JavaScript such as large images. Workaround Disable JavaScript until a version containing these fixes can be installed. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes Please close and restart Mozilla Firefox and/or seamonkey after the update. 4) Package Location and Checksums The preferred method for installing security updates is to use the YaST Online Update (YOU) tool. YOU detects which updates are required and automatically performs the necessary steps to verify and install them. Alternatively, download the update packages for your distribution manually and verify their integrity by the methods listed in Section 6 of this announcement. Then install the packages using the command rpm -Fhv <file.rpm> to apply the update, replacing <file.rpm> with the filename of the downloaded RPM package. x86 Platform: openSUSE 11.1: http://download.opensuse.org/pub/opensuse/update/11.1/rpm/i586/MozillaFirefo... http://download.opensuse.org/pub/opensuse/update/11.1/rpm/i586/MozillaFirefo... http://download.opensuse.org/pub/opensuse/update/11.1/rpm/i586/mozilla-xulru... http://download.opensuse.org/pub/opensuse/update/11.1/rpm/i586/mozilla-xulru... http://download.opensuse.org/pub/opensuse/update/11.1/rpm/i586/mozilla-xulru... http://download.opensuse.org/pub/opensuse/update/11.1/rpm/i586/mozilla-xulru... http://download.opensuse.org/pub/opensuse/update/11.1/rpm/i586/python-xpcom1... http://download.opensuse.org/pub/opensuse/update/11.1/rpm/i586/seamonkey-1.1... http://download.opensuse.org/pub/opensuse/update/11.1/rpm/i586/seamonkey-dom... http://download.opensuse.org/pub/opensuse/update/11.1/rpm/i586/seamonkey-irc... http://download.opensuse.org/pub/opensuse/update/11.1/rpm/i586/seamonkey-mai... http://download.opensuse.org/pub/opensuse/update/11.1/rpm/i586/seamonkey-spe... http://download.opensuse.org/pub/opensuse/update/11.1/rpm/i586/seamonkey-ven... openSUSE 11.0: http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/MozillaFirefo... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/MozillaFirefo... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/mozilla-xulru... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/mozilla-xulru... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/mozilla-xulru... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/mozilla-xulru... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/seamonkey-1.1... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/seamonkey-dom... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/seamonkey-irc... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/seamonkey-mai... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/seamonkey-spe... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/i586/seamonkey-ven... openSUSE 10.3: http://download.opensuse.org/pub/opensuse/update/10.3/rpm/i586/seamonkey-1.1... http://download.opensuse.org/pub/opensuse/update/10.3/rpm/i586/seamonkey-dom... http://download.opensuse.org/pub/opensuse/update/10.3/rpm/i586/seamonkey-irc... http://download.opensuse.org/pub/opensuse/update/10.3/rpm/i586/seamonkey-mai... http://download.opensuse.org/pub/opensuse/update/10.3/rpm/i586/seamonkey-spe... http://download.opensuse.org/pub/opensuse/update/10.3/rpm/i586/seamonkey-ven... x86-64 Platform: openSUSE 11.1: http://download.opensuse.org/pub/opensuse/update/11.1/rpm/x86_64/mozilla-xul... http://download.opensuse.org/pub/opensuse/update/11.1/rpm/x86_64/mozilla-xul... http://download.opensuse.org/pub/opensuse/update/11.1/rpm/x86_64/mozilla-xul... openSUSE 11.0: http://download.opensuse.org/pub/opensuse/update/11.0/rpm/x86_64/mozilla-xul... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/x86_64/mozilla-xul... http://download.opensuse.org/pub/opensuse/update/11.0/rpm/x86_64/mozilla-xul...

The authenticity and integrity of a SUSE security announcement is guaranteed by a cryptographic signature in each announcement. All SUSE security announcements are published with a valid signature. To verify the signature of the announcement, save it as text into a file and run the command gpg --verify <file> replacing <file> with the name of the file where you saved the announcement. The output for a valid signature looks like: gpg: Signature made <DATE> using RSA key ID 3D25D3D9 gpg: Good signature from "SuSE Security Team <security@suse.de>" where <DATE> is replaced by the date the document was signed. If the security team's key is not contained in your key ring, you can import it from the first installation CD. To import the key, use the command gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc - Package authenticity verification: SUSE update packages are available on many mirror FTP servers all over the world. While this service is considered valuable and important to the free and open source software community, the authenticity and the integrity of a package needs to be verified to ensure that it has not been tampered with. The internal rpm package signatures provide an easy way to verify the authenticity of an RPM package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, replacing <file.rpm> with the filename of the RPM package downloaded. The package is unmodified if it contains a valid signature from build@suse.de with the key ID 9C800ACA. This key is automatically imported into the RPM database (on RPMv4-based distributions) and the gpg key ring of 'root' during installation. You can also find it on the first installation CD and at the end of this announcement. - SUSE runs two security mailing lists to which any interested party may subscribe: opensuse-security@opensuse.org - General Linux and SUSE security discussion.
