CVE-2026-27809— psd-tools 安全漏洞

psd-tools: Compression module has unguarded zlib decompression, missing dimension validation, and hardening gaps

psd-tools is a Python package for working with Adobe Photoshop PSD files. Prior to version 1.12.2, when a PSD file contains malformed RLE-compressed image data (e.g. a literal run that extends past the expected row size), decode_rle() raises ValueError which propagated all the way to the user, crashing psd.composite() and psd-tools export. decompress() already had a fallback that replaces failed channels with black pixels when result is None, but it never triggered because the ValueError from decode_rle() was not caught. The fix in version 1.12.2 wraps the decode_rle() call in a try/except so the existing fallback handles the error gracefully.

psd-tools 安全漏洞

psd-tools是psd-tools开源的一款用于读取Adobe Photoshop PSD文件的Python包。 psd-tools 1.12.2之前版本存在安全漏洞，该漏洞源于处理包含格式错误的RLE压缩图像数据的PSD文件时，decode_rle()引发的ValueError未捕获，可能导致崩溃。
