Title
adm-zip 0.5.14 through 0.6.0 Denial of Service via Zero Declared Uncompressed Size
Summary
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.
