USN-3699-1: zziplib vulnerabilities

Releases

• Ubuntu 18.04 ESM
• Ubuntu 17.10
• Ubuntu 16.04 ESM
• Ubuntu 14.04 ESM

Packages

• zziplib - library providing read access on ZIP-archives - library

Details

It was 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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.04

• libzzip-0-13 - 0.13.62-3.1ubuntu0.18.04.1

Ubuntu 17.10

• libzzip-0-13 - 0.13.62-3.1ubuntu0.17.10.1

Ubuntu 16.04

• libzzip-0-13 - 0.13.62-3ubuntu0.16.04.2

Ubuntu 14.04

• libzzip-0-13 - 0.13.62-2ubuntu0.2

In general, a standard system update will make all the necessary changes.
