-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2009.1521 Security Vulnerability in the OSCAR Protocol Plugin for pidgin(1) may Lead to a Denial of Service (DoS) Condition 12 November 2009 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: pidgin Publisher: Sun Microsystems Operating System: Solaris OpenSolaris Impact/Access: Denial of Service -- Remote/Unauthenticated Resolution: Patch/Upgrade CVE Names: CVE-2009-3615 Reference: ASB-2009.1113 Original Bulletin: http://sunsolve.sun.com/search/printfriendly.do?assetkey=1-66-272489-1 Comment: Please note the patch to correct this vulnerability is pending for Solaris 10. - --------------------------BEGIN INCLUDED TEXT-------------------- Security Vulnerability in the OSCAR Protocol Plugin for pidgin(1) may Lead to a Denial of Service (DoS) Condition _________________________________________________________________ Category : Security Release Phase : Workaround Bug Id : 6893676 Product : Solaris 10 Operating System OpenSolaris Date of Workaround Release : 10-Nov-2009 Security vulnerability in the OSCAR protocol plugin for pidgin(1): 1. Impact A security vulnerability in the the OSCAR protocol plugin library, the shared library that adds support for various instant messaging networks to the pidgin(1) Instant Messaging client (previously known as Gaim), may allow remote unprivileged users to cause a Denial of Service (DoS) through an application crash via crafted contact-list data for (1) ICQ and possibly (2) AIM. This issue is also referenced in the following document: CVE-2009-3615 at: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3615 2. Contributing Factors This issue can occur in the following releases: SPARC Platform * Solaris 10 * OpenSolaris based upon builds snv_01 through snv_126 x86 Platform * Solaris 10 * OpenSolaris based upon builds snv_01 through snv_126 Note 1: Solaris 8 and Solaris 9 do not ship Pidgin and therefore are not affected by this issue. Note 2: This issue only affects systems that have affected versions of either the Pidgin IM client installed or the Gaim IM client installed. To determine if either of these are installed, run the following commands: $ /usr/bin/pidgin -v || echo "Pidgin IM client not installed" $ /usr/bin/gaim -v || echo "Gaim IM client not installed" All versions of Pidgin before 2.6.3, and all versions of Gaim after 0.78 are impacted by this issue. The conversion from Gaim to Pidgin occurred in build snv_68 of OpenSolaris and in Solaris 10 patches 119548-11 (for SPARC) and 119549-11 (for x86). Note 3: OpenSolaris distributions may include additional bug fixes above and beyond the build from which it was derived. To determine the base build of OpenSolaris, the following command can be used: $ uname -v snv_86 3. Symptoms If the described issue has been exploited to cause a Denial of Service (DoS), Pidgin will crash, potentially leaving a core file depending on the system configuration. There are no predictable symptoms that would indicate that this issue has been exploited to execute arbitrary code. 4. Workaround To work around this issue until the resolution patches can be applied, do not import contact lists from untrusted sources. 5. Resolution This issue is addressed in the following releases: SPARC Platform * OpenSolaris based upon builds snv_127 or later x86 Platform * OpenSolaris based upon builds snv_127 or later A final resolution is pending completion for Solaris 10.
