USN-3320-1: zziplib vulnerabilities

Publication date

15 June 2017

Overview

zziplib could be made to crash or run programs as your login if it opened a specially crafted file.


Packages

  • zziplib - library providing read access on ZIP-archives

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.
