Mozilla Foundation Security Advisory 2012-19
Title: Miscellaneous memory safety hazards
(rv:11.0/ rv:10.0.3 / rv:220.127.116.11)
Announced: March 13, 2012
Reporter: Mozilla developers and community
Products: Firefox, Thunderbird, SeaMonkey
Fixed in: Firefox 11.0
Firefox ESR 10.0.3
Thunderbird ESR 10.0.3
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 and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products.
Bob Clary reported two bugs that causes crashes that affected Firefox 3.6, Firefox ESR, and Firefox 10.
Christian Holler, Jesse Ruderman, Nils, Michael Bebenita, Dindog, and David Anderson reported memory safety problems and crashes that affect Firefox ESR and Firefox 10.
Jeff Walden reported a memory safety problem in the
array.join function. This bug was independently reported by
Vincenzo Iozzo and Willem Pinckaers
via TippingPoint's Zero Day Initiative Pwn2Own contest.
Masayuki Nakano reported a memory safety problem that affected Mobile Firefox 10.
