Affected packages
• PyPI psd-tools: >= 1.8.37, < 1.9.4 → fixed in 1.9.4
Description
Impact
An issue was discovered in psd-tools before 1.9.4. The Cython implementation of RLE decoding did not check for malformed PSD input data during decoding to the PIL.Image or NumPy format, leading to a Buffer Overflow.
Patches
Users of psd-tools version v1.8.37 to v1.9.3 should upgrade to v1.9.4.
Workarounds
Without Cython present on installation, buffer overflow does not occur but IndexError will be thrown. However, already installed psd-tools with Cython extention should be upgraded.
