Technical details
An unsigned integer underflow in the WritePixels() function occurs when parsing XPM images with both width and height set to zero. The code computes row loop bounds as "h = height - 1" using unsigned arithmetic; with height=0, this underflows to UINT_MAX, causing a near-infinite write loop. The vulnerability requires local file access to provide a malicious XPM file and affects libXpm before version 3.5.19.
Affected products
- Freedesktop libXpm before 3.5.19
