Summary:

Several security issues were fixed in Munin.

Software Description:

Details:

It was discovered that the Munin qmailscan plugin incorrectly handled

permissions. An attacker obtaining privileges of the munin user could use
this issue to escalate privileges to root. (CVE-2012-3512)

execute arbitrary code with the privileges of the web server. This issue
only affected Ubuntu 12.10. (CVE-2012-3513)
