No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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.
