3 June 2015

t1utils vulnerability

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

  • Ubuntu 14.10
  • Ubuntu 14.04 LTS

Summary

t1utils could be made to crash or run programs as your login if it opened a specially crafted file.

Software Description

  • t1utils - Collection of simple Type 1 font manipulation programs

Details

Jakub Wilk discovered that t1utils incorrectly handled certain malformed fonts. If a user or automated system were tricked into opening a specially crafted font, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges.

Update instructions

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

Ubuntu 14.10
t1utils - 1.37-2.1ubuntu0.1
Ubuntu 14.04 LTS
t1utils - 1.37-2ubuntu1.1

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