-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Summary Report Announcement ID: SUSE-SR:2006:010 Date: Fri, 12 May 2006 16:00:00 +0000 Cross-References: CVE-2005-1111, CVE-2005-1229, CVE-2005-4268 CVE-2006-1546, CVE-2006-1547, CVE-2006-1548 CVE-2006-1834, CVE-2006-1932, CVE-2006-1933 CVE-2006-1934, CVE-2006-1935, CVE-2006-1936 CVE-2006-1937, CVE-2006-1938, CVE-2006-1939 CVE-2006-1940, CVE-2006-1989, CVE-2006-2069 Content of this advisory: 1) Solved Security Vulnerabilities: - opera integer overflow in style sheet handling - pdns remote denial of service attack - cpio various issues - ethereal various issues - clamav freshclam buffer overflow - Apache struts various problems 2) Pending Vulnerabilities, Solutions, and Work-Arounds: - SUSE Linux 10.1 update problems 3) Authenticity Verification and Additional Information ______________________________________________________________________________ 1) Solved Security Vulnerabilities To avoid flooding mailing lists with SUSE Security Announcements for minor issues, SUSE Security releases weekly summary reports for the low profile vulnerability fixes. The SUSE Security Summary Reports do not list md5 sums or download URLs like the SUSE Security Announcements that are released for more severe vulnerabilities. Fixed packages for the following incidents are already available on our FTP server and via the YaST Online Update. - Opera integer overflow in style sheet handling An integer signedness error in Opera before 8.54 allows remote attackers to execute arbitrary code via long values in a style sheet attribute, which pass a length check. This affects all SUSE Linux versions and is tracked by the Mitre CVE ID CVE-2006-1834. - pdns remote denial of service attack Remote attackers could crash the PowerDNS (pdns) server by sending malformed packets. This only affects SUSE Linux 10.1 and is tracked by the Mitre CVE ID CVE-2006-2069. - cpio various issues CPIO has been updated to fix the following security problems: - Very large files could cause a buffer overflow on 64bit platforms (CVE-2005-4268) - When extracting an archive into a directory that is writable by other users, a user could trick cpio into changing the permissions of files outside that directory (CVE-2005-1111). - Relative paths in cpio archives could be used to write a file into an arbitrary directory when extracting the archive (CVE-2005-1229). This problem affects all SUSE Linux based products. - ethereal various issues Various security problems were fixed in ethereal, these could have denial of service attacks or even arbitrary code execution as impact. The tracking Mitre CVE IDs of the fixed issues are: CVE-2006-1932, CVE-2006-1933, CVE-2006-1934, CVE-2006-1935, CVE-2006-1936, CVE-2006-1937, CVE-2006-1938, CVE-2006-1939, CVE-2006-1940 - clamav freshclam buffer overflow Clamav was updated to version 0.88.2 fixes among other things the following security problem: - A buffer overflow in the freshclam program might allow remote web servers to execute arbitrary code via long HTTP headers (CVE-2006-1989). All SUSE Linux based products containing clamav were affected. - Apache struts various problems Three security problems were fixed in Apache Struts: 1.) Apache Software Foundation (ASF) Struts before 1.2.9 allows remote attackers to bypass validation via a request with a 'org.apache.struts.taglib.html.Constants.CANCEL' parameter, which causes the action to be canceled but would not be detected from applications that do not use the isCancelled check. (CVE-2006-1546) 2.) ActionForm in Apache Software Foundation (ASF) Struts before 1.2.9 with BeanUtils 1.7 allows remote attackers to cause a denial of service via a multipart/form-data encoded form with a parameter name that references the public getMultipartRequestHandler method, which provides further access to elements in the CommonsMultipartRequestHandler implementation and BeanUtils. (CVE-2006-1547) 3.) Cross-site scripting (XSS) vulnerability in (1) LookupDispatchAction and possibly (2) DispatchAction and (3) ActionDispatcher in Apache Software Foundation (ASF) Struts before 1.2.9 allows remote attackers to inject arbitrary web script or HTML via the parameter name, which is not filtered in the resulting error message. (CVE-2006-1548) SUSE Linux 9.3 and 10.0 were affected by these problems. ______________________________________________________________________________ 2) Pending Vulnerabilities, Solutions, and Work-Arounds - SUSE Linux 10.1 update problems Installation of the opera and pdns updates on SUSE Linux 10.1 might be problematic. We are aware of 2 problems: - zen-updater is not able to install the updates. Workaround: Use YaST Online Update directly, started via YaST2 control center. - YaST crashes when installing packages directly from the online update source. The installer tries to install packages directly from the online update source instead of your CDs (in case of security updates) to avoid intermediate steps. This is not fully working yet so you might experience crashes. Workaround: Disable the remote update source during install of this package and re enable it afterward. - MySQL various issues MySQL 5.0.21 was released fixing various security problems, including information leaks and a remote code execution. We are currently preparing updates for these problems. - Next Kernel Update A kernel update for all products is in preparation and will likely be released in the next week. ______________________________________________________________________________ 3) Authenticity Verification and Additional Information - Announcement authenticity verification: SUSE security announcements are published via mailing lists and on Web sites. 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 containing 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 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 included at the end of this announcement. - SUSE runs two security mailing lists to which any interested party may subscribe: suse-security@suse.com - General Linux and SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to <suse-security-subscribe@suse.com>. suse-security-announce@suse.com - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to <suse-security-announce-subscribe@suse.com>. For general information or the frequently asked questions (FAQ) send mail to <suse-security-info@suse.com> or <suse-security-faq@suse.com>. ===================================================================== SUSE's security contact is <security@suse.com> or <security@suse.de>.
