Original advisory details:
If was discovered that Firefox could be made to access freed memory. If a user were tricked into viewing a malicious site, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. This issue only affected Ubuntu 8.04 LTS. (CVE-2010-1121)
Several flaws were discovered in the browser engine of Firefox. If a user were tricked into viewing a malicious site, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2010-1200, CVE-2010-1201, CVE-2010-1202, CVE-2010-1203)
A flaw was discovered in the way plugin instances interacted. An attacker could potentially exploit this and use one plugin to access freed memory from a second plugin to execute arbitrary code with the privileges of the user invoking the program. (CVE-2010-1198)
An integer overflow was discovered in Firefox. If a user were tricked into viewing a malicious site, an attacker could overflow a buffer and cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2010-1196)
Martin Barbella discovered an integer overflow in an XSLT node sorting routine. An attacker could exploit this to overflow a buffer and cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2010-1199)
Michal Zalewski discovered that the focus behavior of Firefox could be subverted. If a user were tricked into viewing a malicious site, a remote attacker could use this to capture keystrokes. (CVE-2010-1125)
Ilja van Sprundel discovered that the ‘Content-Disposition: attachment’ HTTP header was ignored when ‘Content-Type: multipart’ was also present. Under certain circumstances, this could potentially lead to cross-site scripting attacks. (CVE-2010-1197)
Amit Klein discovered that Firefox did not seed its random number generator often enough. An attacker could exploit this to identify and track users across different web sites. (CVE-2008-5913)
