PLATFORM: Red Hat Desktop (v. 3), (v. 4) Red Hat Enterprise Linux AS, ES, WS (v. 3), (v. 4) DAMAGE: 1) A remote attacker could send a specially crafted away message to a Gaim user logged into AIM or ICQ that could result in arbitrary code execution. 2) A remote attacker could attempt to upload a file with a specially crafted name to a user logged into AIM or ICQ, causing Gaim to crash. 3) A remote attacker could send a specially crafted message to a Gaim user logged into Gadu Gadu, causing Gaim to crash. SOLUTION: Upgrade to appropriate version. ______________________________________________________________________________ VULNERABILITY The risk is HIGH. Due to a remote attacker sending a specially ASSESSMENT: crafted away message to a Gaim user logged into AIM or ICQ that could result in arbitrary code execution. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/p-270.shtml ORIGINAL BULLETIN: https://rhn.redhat.com/errata/RHSA-2005-627.html CVE/CAN: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CAN-2005-2102 CAN-2005-2103 CAN-2005-2370 ______________________________________________________________________________ [***** Start Red Hat RHSA-2005:627-11 *****] Critical: gaim security update Advisory: RHSA-2005:627-11 Type: Security Advisory Issued on: 2005-08-09 Last updated on: 2005-08-09 Affected Products: Red Hat Desktop (v. 3) Red Hat Desktop (v. 4) Red Hat Enterprise Linux AS (v. 3) Red Hat Enterprise Linux AS (v. 4) Red Hat Enterprise Linux ES (v. 3) Red Hat Enterprise Linux ES (v. 4) Red Hat Enterprise Linux WS (v. 3) Red Hat Enterprise Linux WS (v. 4) CVEs (cve.mitre.org): CAN-2005-2102 CAN-2005-2103 CAN-2005-2370 Details An updated gaim package that fixes multiple security issues is now available. This update has been rated as having critical security impact by the Red Hat Security Response Team. Gaim is an Internet Messaging client. A heap based buffer overflow issue was discovered in the way Gaim processes away messages. A remote attacker could send a specially crafted away message to a Gaim user logged into AIM or ICQ that could result in arbitrary code execution. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-2103 to this issue. Daniel Atallah discovered a denial of service issue in Gaim. A remote attacker could attempt to upload a file with a specially crafted name to a user logged into AIM or ICQ, causing Gaim to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-2102 to this issue. A denial of service bug was found in Gaim's Gadu Gadu protocol handler. A remote attacker could send a specially crafted message to a Gaim user logged into Gadu Gadu, causing Gaim to crash. Please note that this issue only affects PPC and IBM S/390 systems running Gaim. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-2370 to this issue. Users of gaim are advised to upgrade to this updated package, which contains backported patches and is not vulnerable to these issues. Solution Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.
