Threats tagged 'ghsa-9hj8-73fh-9963'

A denial of service vulnerability exists in the zip crate versions 5.1.0 up to but not including 9.0.0 when the legacy-zip feature is enabled. An attacker can craft a malicious ZIP64 archive with an uncompressed size set to an extremely large value, causing a capacity overflow panic in the Shrink decoder during extraction. This panic terminates the affected process, leading to denial of service. The issue arises because the decoder reserves output buffer capacity based on the uncompressed size from ZIP metadata before validating the compressed data size. This vulnerability is fixed in version 9.0.0.
