Synopsis
========
A hash collision vulnerability in Mono allows remote attackers to cause
a Denial of Service condition.
Background
==========
Mono is an open source implementation of Microsoft's .NET Framework.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/mono < 2.10.9-r2 >= 2.10.9-r2
Description
===========
Mono does not properly randomize hash functions for form posts to
protect against hash collision attacks.
Impact
======
A remote attacker could send specially crafted parameters, possibly
resulting in a Denial of Service condition.
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-2.10.9-r2"
