CVE-2014-1947

Application crash via undersized PSD layer-name buffer

Published Feb 17, 2020 · Updated Aug 6, 2024

Stack buffer overflow in ImageMagick 6.5.4 and earlier allows attackers to crash applications via a PSD image containing many layers. WritePSDImage in coders/psd.c formats an autogenerated L%02ld layer name into a four-byte stack buffer, which overflows at 100 layers. Processing attacker-influenced layered PSD content is required; corrupted stack state crashes the process and can enable arbitrary code execution.
