Scientific Linux Security Update : thunderbird on SL5.x, SL6.x i386/x86_64 (20130625)
Critical Nessus Plugin ID 66984
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionSeveral flaws were found in the processing of malformed content.
Malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2013-1682, CVE-2013-1684, CVE-2013-1685, CVE-2013-1686, CVE-2013-1687, CVE-2013-1690)
It was found that Thunderbird allowed data to be sent in the body of XMLHttpRequest (XHR) HEAD requests. In some cases this could allow attackers to conduct Cross-Site Request Forgery (CSRF) attacks.
Timing differences in the way Thunderbird processed SVG image files could allow an attacker to read data across domains, potentially leading to information disclosure. (CVE-2013-1693)
Two flaws were found in the way Thunderbird implemented some of its internal structures (called wrappers). An attacker could use these flaws to bypass some restrictions placed on them. This could lead to unexpected behavior or a potentially exploitable crash.
0.7 ESR, which corrects these issues. After installing the update, Thunderbird must be restarted for the changes to take effect.
SolutionUpdate the affected thunderbird and / or thunderbird-debuginfo packages.
