Description Huzaifa S. Sidhpurwala 2012-11-19 10:06:14 UTC
Security researcher miaubiz used the Address Sanitizer tool to discover a series critically rated of use-after-free, buffer overflow, and memory corruption issues in shipped software. These issues are potentially exploitable, allowing for remote code execution. We would also like to thank miaubiz for reporting two additional use-after-free and memory corruption issues 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.

These issues affect Firefox 17 and Thunderbird 17 only.

Acknowledgements:

Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges miaubiz as the original reporter.

Statement:

This issue does not affect the version of firefox and thunderbird as shipped with Red Hat Enterprise Linux 5 and 6
