Mozilla Foundation Security Advisory 2011-09
Crash caused by corrupted JPEG image
- March 1, 2011
- Jordi Chancel
- Firefox, Thunderbird
- Fixed in
- Firefox 3.6.14
- Thunderbird 3.1.8
Security researcher Jordi Chancel reported that a JPEG image could be constructed that would be decoded incorrectly, causing data to be written past the end of a buffer created to store the image. An attacker could potentially craft such an image that would cause malicious code to be stored in memory and then later executed on a victim's computer.
Firefox 3.5 was not affected by this issue.
