Ubuntu Security Notice USN-1979-1
September 30, 2013
A security issue affects these releases of Ubuntu and its derivatives:
Summary:
txt2man could be made to overwrite files.
Software Description:
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.
