Summary: An updated gaim package that fixes several security issues is now available. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 3. Problem description: Gaim is an instant messenger client that can handle multiple protocols. Buffer overflow bugs were found in the Gaim MSN protocol handler. In order to exploit these bugs, an attacker would have to perform a man in the middle attack between the MSN server and the vulnerable Gaim client. Such an attack could allow arbitrary code execution. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0500 to this issue. Buffer overflow bugs have been found in the Gaim URL decoder, local hostname resolver, and the RTF message parser. It is possible that a remote attacker could send carefully crafted data to a vulnerable client and lead to a crash or arbitrary code execution. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0785 to this issue. A shell escape bug has been found in the Gaim smiley theme file installation. When a user installs a smiley theme, which is contained within a tar file, the unarchiving of the data is done in an unsafe manner. An attacker could create a malicious smiley theme that would execute arbitrary commands if the theme was installed by the victim. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0784 to this issue. An integer overflow bug has been found in the Gaim Groupware message receiver. It is possible that if a user connects to a malicious server, an attacker could send carefully crafted data which could lead to arbitrary code execution on the victims machine. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0754 to this issue. Users of Gaim are advised to upgrade to this updated package which contains Gaim version 0.82 and is not vulnerable to these issues. 4.
