Mandriva Linux Security Advisory 2013-105

Mandriva Linux Security Advisory 2013-105
Posted Apr 11, 2013
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2013-105 - The qmailscan plugin for Munin before 2.0 rc6 allows local users to overwrite arbitrary files via a symlink attack on temporary files with predictable names. Munin before 2.0.6 stores plugin state files that run as root in the same group-writable directory as non-root plugins, which allows local users to execute arbitrary code by replacing a state file, as demonstrated using the smart_ plugin. munin-cgi-graph in Munin before 2.0.6, when running as a CGI module under Apache, allows remote attackers to load new configurations and create files in arbitrary directories via the logdir command.

Package : munin
Date : April 10, 2013
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Updated munin packages fix security vulnerabilities:

The qmailscan plugin for Munin before 2.0 rc6 allows local users to
overwrite arbitrary files via a symlink attack on temporary files
with predictable names (CVE-2012-2103).

Munin before 2.0.6 stores plugin state files that run as root in
the same group-writable directory as non-root plugins, which allows
local users to execute arbitrary code by replacing a state file,
as demonstrated using the smart_ plugin (CVE-2012-3512).

munin-cgi-graph in Munin before 2.0.6, when running as a CGI module
under Apache, allows remote attackers to load new configurations
and create files in arbitrary directories via the logdir command
(CVE-2012-3513).
