Ubuntu 12.04 LTS / 12.10 / 13.04 : txt2man vulnerability (USN-1979-1)

Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected txt2man package.

Risk factor :

Low / CVSS Base Score : 3.3
(CVSS2#AV:L/AC:M/Au:N/C:N/I:P/A:P)
CVSS Temporal Score : 2.9
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
