Title: Mono: Insecure temporary file creation
Date: November 28, 2006
Bugs: #150264
ID: 200611-23

Synopsis
========
Mono is vulnerable to linking attacks, potentially allowing a local
user to overwrite arbitrary files.
Background
==========
Mono provides the necessary software to develop and run .NET client and
server applications.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/mono < 1.1.13.8.1 >= 1.1.13.8.1
Description
===========
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.
Resolution
==========
All Mono users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/mono-1.1.13.8.1"
References
