uv allows ZIP payload obfuscation through parsing differentials

ImpactIn versions 0.8.5 and earlier of uv, remote ZIP archives were handled in a streamwise fashion, and file entries were not reconciled against the archive's central directory. This enabled two parser differentials against other Python package installers:1. An attacker could contrive a ZIP...

ZIP Payload Obfuscation Through Parsing Differentials

uv is vulnerable to ZIP payload obfuscation through parsing differentials. The vulnerability is due to improper ZIP archive validation due to failure to reconcile file entries against the central directory, allowing attackers to craft archives with inconsistent or stacked ZIPs that behave...
