Mozilla Releases Another New Version of Firefox to Fix Yet Another Critical Vulnerability

(LiveHacking.Com) – Less then 7 days after the release of Firefox 10.0.1, Mozilla has now released a new version of Firefox (10.0.2) and Thunderbird (also 10.0.2) to fix a Critical libpng integer overflow vulnerability. The bug, which affects Firefox, Thunderbird, SeaMonkey, is an integer overflow in the libpng library that can lead to a heap-buffer overflow when decompressing certain PNG images. This leads to a crash, which may be potentially exploitable.

The presence of the bug first came to light when Google released Chrome 17.0.963.56 to fix the integer overflow in libpng where it was noted that the bug allows remote attackers to cause a denial of service. According to the Chromium source code the fix includes a check for both truncation (64-bit platforms) and integer overflow.

Also fixed in 10.0.2 is a bug where Java applets sometimes caused text input to become unresponsive (bug 718939).
