The Mozilla SVG viewer contains an integer overflow vulnerability. This vulnerability may allow an attacker to execute arbitrary code, or create a denial-of-service condition.
Scalable Vector Graphics (SVG) is an XML markup language for describing and displaying animated or static vector graphics. Mozilla Firefox includes a native SVG viewer, other Mozilla projects may use the Adobe SVG viewer.
The Mozilla SVG viewer fails to properly validate size parameters supplied to a memory allocation routine allowing an integer overflow to occur. This vulnerability could cause an undersized buffer to be allocated. When data is copied to that buffer, a heap-based buffer overflow may occur. An attacker may be able to exploit this vulnerability by convincing a user to go to a website that hosts a specially crafted SVG file.
A remote, unauthenticated attacker may be able to execute arbitrary code, or create a denial-of-service condition.
Mozilla credits Tom Ferris for reporting this vulnerability.
