Descriptions

Integer overflow in Mozilla Firefox and Thunderbird 1.x before 1.5.0.2 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0.1 allows remote attackers to execute arbitrary code via a large number in the CSS letter-spacing property that leads to a heap-based buffer overflow.

This vulnerability allows attackers to execute arbitrary code on vulnerable installations of the Mozilla/Firefox web browser and Thunderbird e-mail client. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious e-mail.
The specific flaw is due to incorrect handling of the CSS "letter-spacing" element. By specifying a large number, an attacker can overflow an integer used during memory allocation. The under-allocated buffer is later used to store user-supplied data leading to an exploitable heap overflow.
