Details

Agostino Sarubbo discovered that zziplib incorrectly handled certain
malformed ZIP files. If a user or automated system were tricked into
opening a specially crafted ZIP file, a remote attacker could cause zziplib
to crash, resulting in a denial of service, or possibly execute arbitrary
code.
