-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Summary Report Announcement ID: SUSE-SR:2007:025 Date: Wed, 05 Dec 2007 12:00:00 +0000 Cross-References: CVE-2007-1659, CVE-2007-1660, CVE-2007-5198 CVE-2007-5269, CVE-2007-5380, CVE-2007-5497 CVE-2007-5623, CVE-2007-5846, CVE-2007-6109 CVE-2007-6110, CVE-2007-6130 Content of this advisory: 1) Solved Security Vulnerabilities: - net-snmp denial of service problems - htdig XSS attacks - e2fsprogs overflows in libext2fs - nagios-plugins security problems - libpng denial of service problem - emacs overflow in command line - rubygem-actionpack session access - gnump3d restriction bypass - glib2 affected by PCRE problems 2) Pending Vulnerabilities, Solutions, and Work-Arounds: - None listed this week. 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. - net-snmp denial of service problems Net-snmp was updated to fix the following bugs: - default and configurable maximum number of varbinds returnable to a GETBULK request (CVE-2007-5846) - crash when smux peers were configured with empty passwords - the UCD-SNMP-MIB::memCached.0 SNMP object was missing - the snmptrap command from the net-snmp package sends traps per default on the wrong port. - htdig XSS attacks A flaw in the htsearch Program could be exploited by attackers to conduct cross site scripting (XSS) attacks. (CVE-2007-6110) - e2fsprogs overflows in libext2fs e2fsprogs has been updated to fix several integer overflows in memory allocating code. Programs that use libext2fs are therefore vulnerable to memory corruptions that can lead to arbitrary code execution while loading a specially crafted image. (CVE-2007-5497) Updates have been provided for all SUSE Linux based products. - nagios-plugins security problems Two security problems in Nagios plugins were fixed for all SUSE Linux based distributions: - fixed possible buffer overflow during HTTP Location header parsing in check_http (CVE-2007-5198) - fixed possible buffer overflow during snmpget parsing in check_snmp (CVE-2007-5623) - libpng denial of service problem A security problem in libpng was fixed where specially crafted PNG files could crash applications attempting to open such a file (CVE-2007-5269). Updated packages have been releases for all distributions. - emacs overflow in command line A buffer overflow was fixed in emacs that can be triggered over the command-line (CVE-2007-6109). Updates have been released for all distributions containing emacs. - rubygem-actionpack session access A security problem in the Ruby on Rails package rubygem-actionpack was fixed, where malicious users could specify their session-ID in the URL and so could gain access to an authenticated session that way (CVE-2007-5380). The package was fixed in openSUSE 10.3 and SUSE Linux Enterprise 10. - gnump3d restriction bypass A restriction bypass in plugins of the gnump3d package was fixed. (CVE-2007-6130) Updated packages have been provided for SUSE Linux 10.1, openSUSE 10.2 and 10.3. - glib2 affected by PCRE problems glib2 on openSUSE 10.3 included a copy of the PCRE library. This copy has been disabled and glib2 is now linking against the system PCRE, which has those problems fixed. (CVE-2007-1659, CVE-2007-1660) ______________________________________________________________________________ 2) Pending Vulnerabilities, Solutions, and Work-Arounds None listed this 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 " 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 to verify the signature of the package, replacing 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: opensuse-security@opensuse.org - General Linux and SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to . opensuse-security-announce@opensuse.org - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to . ===================================================================== SUSE's security contact is or .
