Summary

ImageMagick versions from 7.0.0-0 before 7.1.2-33 and versions before 6.9.13-58 are affected. A pointer arithmetic overflow in DecodeImage() in coders/pict.c on 32-bit builds lets crafted row, column and bytes-per-line values bypass bounds checks, causing a heap buffer underwrite (CWE-124). An unauthenticated attacker who supplies a crafted PICT file can write up to 128 controlled bytes below the heap buffer, causing crashes or code execution.

Description from the CNA

ImageMagick before 7.1.2-33 and 6.9.13-58 contains a heap buffer underwrite vulnerability in DecodeImage() in coders/pict.c on 32-bit builds due to pointer arithmetic overflow. Attackers can supply a crafted PICT file with maximized row, column and bytes-per-line values to bypass bounds checks and write up to 128 controlled bytes below the heap buffer, causing crashes or code execution.
