Mozilla Thunderbird 10.x < 10.0.2 'png_decompress_chunk' Integer Overflow

High

Synopsis

The remote host has a mail client installed that is potentially affected by an integer overflow vulnerability.

Description

Versions of Thunderbird 10.x earlier than 10.0.2 are potentially affected by an integer overflow error in 'libpng', a library used by this application. When decompressing certain PNG image files, this error can allow a heap-based buffer overflow which can crash the application or potentially allow code execution.

Solution

Upgrade to Thunderbird 10.0.2 or later.
