Summary: Updated thunderbird packages that fix several security bugs are now available for Red Hat Enterprise Linux 4. This update has been rated as having critical security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 3. Problem description: Mozilla Thunderbird is a standalone mail and newsgroup client. Several flaws were found in the way Thunderbird processes certain malformed Javascript code. A malicious HTML mail message could cause the execution of Javascript code in such a way that could cause Thunderbird to crash or execute arbitrary code as the user running Thunderbird. (CVE-2006-5463, CVE-2006-5747, CVE-2006-5748) Several flaws were found in the way Thunderbird renders HTML mail messages. A malicious HTML mail message could cause the mail client to crash or possibly execute arbitrary code as the user running Thunderbird. (CVE-2006-5464) A flaw was found in the way Thunderbird verifies RSA signatures. For RSA keys with exponent 3 it is possible for an attacker to forge a signature that would be incorrectly verified by the NSS library. Thunderbird as shipped trusts several root Certificate Authorities that use exponent 3. An attacker could have created a carefully crafted SSL certificate which would be incorrectly trusted when their site was visited by a victim. This flaw was previously thought to be fixed in Thunderbird 1.5.0.7, however Ulrich Kuehn discovered the fix was incomplete (CVE-2006-5462) Users of Thunderbird are advised to upgrade to this update, which contains Thunderbird version 1.5.0.8 that corrects these issues. 4. 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. 5. Bug IDs fixed (http://bugzilla.redhat.com/): 214450 - CVE-2006-5462 Multiple thunderbird vulnerabilities (CVE-2006-5463, CVE-2006-5464, CVE-2006-5747, CVE-2006-5748) 6.
