GLSA-200611-23 : Mono: Insecure temporary file creation

This script is Copyright (C) 2006-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200611-23
(Mono: Insecure temporary file creation)

Sebastian Krahmer of the SuSE Security Team discovered that the
System.CodeDom.Compiler classes of Mono create temporary files with
insecure permissions.

Impact :

A local attacker could create links in the temporary file directory,
pointing to a valid file somewhere on the filesystem. When an affected
class is called, this could result in the file being overwritten with
the rights of the user running the script.

Workaround :

There is no known workaround at this time.

Solution :

All Mono users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-lang/mono-1.1.13.8.1'

Risk factor :

Medium / CVSS Base Score : 6.2
