AI-suggested
If you cannot patch yet, avoid processing untrusted ZIP archives with adm-zip versions >=0.5.14 <0.6.1 or implement additional input validation to detect suspicious ZIP entries declaring zero uncompressed size.
Description
adm-zip versions 0.5.14 through 0.6.0 fail to apply zlib decompression output limits when ZIP entries declare zero uncompressed size. Attackers can craft malicious ZIP archives with highly compressible entries declaring zero size to exhaust memory and cause denial of service.
