Miscellaneous memory safety hazards (rv:24.0 / rv:17.0.9)

Announced

Reporter

Mozilla Developers

Impact

Critical

Products

Firefox, Firefox ESR, SeaMonkey, Thunderbird, Thunderbird ESR

Fixed in

• Firefox 24
• Firefox ESR 17.0.9
• SeaMonkey 2.21
• Thunderbird 24
• Thunderbird ESR 17.0.9

Description

Mozilla developers identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these bugs 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.

In general these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled, but are potentially a risk in browser or browser-like contexts.
