Description Josh Bressers 2009-07-16 10:08:08 EDT
Mozilla developers and community members identified and fixed several
stability bugs in the browser engine used in Firefox and other
Mozilla-based products. Some of these crashes showed evidence of memory
corruption under certain circumstances and we presume that with enough
effort at least some of these could be exploited to run arbitrary code.

monarch2020 reported an integer overflow in a base64 decoding function.

MITRE's CVE-2009-2463 entry:

Integer overflow in a base64 decoding function in Mozilla Firefox
before 3.0.12 and Thunderbird allows remote attackers to cause a
denial of service (memory corruption and application crash) or
possibly execute arbitrary code via unspecified vectors.
