15th June, 2017

zziplib vulnerabilities

A security issue affects these releases of Ubuntu and its
derivatives:

  • Ubuntu 17.04
  • Ubuntu 16.10
  • Ubuntu 16.04 LTS
  • Ubuntu 14.04 LTS

Summary

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

Software description

  • 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.
