Title: LibTiff TIFFToRGB Denial of Service Vulnerability
Severity: MODERATE
Description:
LibTIFF is a library designed to facilitate the reading and manipulation of Tag Image File Format (TIFF) files. It is freely available for UNIX and UNIX-like operating systems as well as Microsoft Windows.
LibTIFF is affected by a denial-of-service vulnerability. Specifically, the 'TIFFToRGB' function improperly handles the Yr/Yg/Yb values when they exceed the YCR/YCG/YCB values. Malicious TIFF image files can trigger an out-of-bounds memory read, causing an affected application to crash.
An attacker can exploit this vulnerability to cause denial-of-service conditions in applications using the affected library.
