·
Updated

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.

================================================================= ==3298==ERROR: AddressSanitizer: heap-buffer-overflow on address 0xf512eb00 at pc 0xf76760b5 bp 0xffc1dfb8 sp 0xffc1dfa8 READ of size 8 at 0xf512eb00 thread T0 #0 0xf76760b4 in ReadPSDChannelRLE coders/psd.c:1141

Other sources

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.
