Detailsinfo

A vulnerability was found in Apple Mac OS X up to 10.4.5 (Operating System). It has been classified as critical. This affects the function lzwdecodevector of the component ImageIO. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Heap-based buffer overflow in the LZWDecodeVector function in Mac OS X before 10.4.6, as used in applications that use ImageIO or AppKit, allows remote attackers to execute arbitrary code via crafted TIFF images.

The bug was discovered 04/03/2006. The weakness was released 04/20/2006 by Tom Ferris (McAfee) with McAfee AVERT Labs (Website). The advisory is shared at us-cert.gov.
