CVE-2026-56367

ImageMagick before 7.1.2-15 and 6.9.x before 6.9.13-40 contains an integer overflow in the PSB (PSD v2) RLE decoding path (ReadPSDChannelRLE in coders/psd.c) that causes a heap out-of-bounds read on 32-bit builds. Processing a crafted PSB file can lead to information disclosure or a crash.

An integer overflow in the PSB (PSD v2) RLE decoding path causes a heap out-of-bounds read on 32-bit builds. This can lead to information disclosure or a crash when processing crafted PSB files.
