Mozilla Foundation Security Advisory 2014-01
Title: Miscellaneous memory safety hazards
(rv:27.0 / rv:24.3)
Announced: February 4, 2014
Reporter: Mozilla Developers
Products: Firefox, Thunderbird, Seamonkey
Fixed in: Firefox 27
Firefox ESR 24.3
Mozilla developers and community identified 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 and Seamonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts.
Christian Holler, Terrence Cole, Jesse Ruderman, Gary Kwong, Eric Rescorla, Jonathan Kew, Dan Gohman, Ryan VanderMeulen, and Sotaro Ikeda reported memory safety problems and crashes that affect Firefox ESR 24.2 and Firefox 26.
Gary Kwong, Christian Holler, Jesse Ruderman, Carsten Book, Andrew Sutherland, Byron Campen, Nicholas Nethercote, Paul Adenot, David Baron, Julian Seward, and Dan Gohman reported memory safety problems and crashes that affect Firefox 26.
Carsten Book reported a memory safety problem and crash that affects Firefox ESR 24.3, which has been fixed in Firefox ESR 24.4.
