CVE-2014-1958Network attack vector

Code execution via unchecked PSD RLE expansion

Published Feb 6, 2020 · Updated Aug 6, 2024

Buffer overflow in ImageMagick before 6.8.8-5 allows remote attackers to execute code by causing a crafted RLE-compressed PSD image to be opened. DecodePSDPixels checks only the current output index before expanding the next run, so a run whose decoded length exceeds the remaining buffer overwrites allocated pixel storage. Exploitation requires a user or automated system to open the file; the resulting corruption can crash ImageMagick or execute code with that process's privileges.
