A vulnerability was found in Mozilla Firefox up to 1.0.6 (Web Browser). It has been classified as critical. This affects an unknown code of the component XBM Image Handler. The manipulation with an unknown input leads to a heap-based overflow vulnerability. CWE is classifying the issue as CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Heap-based buffer overflow in Firefox before 1.0.7 and Mozilla Suite before 1.7.12 allows remote attackers to execute arbitrary code via an XBM image file that ends in a large number of spaces instead of the expected end tag.
