Synopsis :

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

Description :

It was discovered that the Munin qmailscan plugin incorrectly handled
temporary files. A local attacker could use this issue to possibly
overwrite arbitrary files. This issue only affected Ubuntu 10.04 LTS,
Ubuntu 11.10, and Ubuntu 12.04 LTS. (CVE-2012-2103)

It was discovered that Munin incorrectly handled plugin state file
permissions. An attacker obtaining privileges of the munin user could
use this issue to escalate privileges to root. (CVE-2012-3512)

alternate configuration file. A remote attacker could possibly use
this issue to execute arbitrary code with the privileges of the web
server. This issue only affected Ubuntu 12.10. (CVE-2012-3513).

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.
