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. Two flaws were found in the way Thunderbird processed certain regular expressions. A malicious HTML email could cause a crash or possibly execute arbitrary code as the user running Thunderbird. (CVE-2006-4565, CVE-2006-4566) A flaw was found in the Thunderbird auto-update verification system. An attacker who has the ability to spoof a victim's DNS could get Firefox to download and install malicious code. In order to exploit this issue an attacker would also need to get a victim to previously accept an unverifiable certificate. (CVE-2006-4567) A flaw was found in the handling of Javascript timed events. A malicious HTML email could crash the browser or possibly execute arbitrary code as the user running Thunderbird. (CVE-2006-4253) Daniel Bleichenbacher recently described an implementation error in RSA signature verification. For RSA keys with exponent 3 it is possible for an attacker to forge a signature that which would be incorrectly verified by the NSS library. (CVE-2006-4340) A flaw was found in Thunderbird that triggered when a HTML message contained a remote image pointing to a XBL script. An attacker could have created a carefully crafted message which would execute Javascript if certain actions were performed on the email by the recipient, even if Javascript was disabled. (CVE-2006-4570) A number of flaws were found in Thunderbird. A malicious HTML email could cause a crash or possibly execute arbitrary code as the user running Thunderbird. (CVE-2006-4571) Users of Thunderbird are advised to upgrade to this update, which contains Thunderbird version 1.5.0.7 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.
