Title: Use-after-free, out of bounds read, and buffer overflow issues found using Address Sanitizer
Impact: Critical
Announced: February 19, 2013
Reporter: Abhishek Arya
Products: Firefox, Thunderbird, SeaMonkey

Fixed in: Firefox 19.0
  Firefox ESR 17.0.3
  Thunderbird 17.0.3
  Thunderbird ESR 17.0.3
  SeaMonkey 2.16

Description

Security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team used the Address Sanitizer tool to discover a series of use-after-free, out of bounds read, and buffer overflow problems rated as low to critical security issues in shipped software. Some of these issues are potentially exploitable, allowing for remote code execution. We would also like to thank Abhishek for reporting four additional use-after-free and out of bounds write flaws introduced during Firefox development that were fixed before general release.

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.
