Ubuntu Security Notice USN-1979-1
September 30, 2013

txt2man vulnerability
==========================================================================

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

- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

txt2man could be made to overwrite files.

Software Description:
- txt2man: Converts flat ASCII text to man page format

Details:

Patrick J Cherry discovered that txt2man contained leftover debugging code
that incorrectly created a temporary file. A local attacker could possibly
use this issue to overwrite arbitrary files. In the default Ubuntu
installation, this should be prevented by the Yama link restrictions.

Update instructions:

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

Ubuntu 13.04:
  txt2man                         1.5.5-4ubuntu0.13.04.1

Ubuntu 12.10:
  txt2man                         1.5.5-4ubuntu0.12.10.1

Ubuntu 12.04 LTS:
  txt2man                         1.5.5-4ubuntu0.12.04.1

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