Severity: normal
Exploitable: remote
Date: May 18, 2014
Bug(s): #433768
ID: 201405-16

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: dev-lang/mono
Vulnerable: < 2.10.9-r2
Unaffected: >= 2.10.9-r2
Architectures: All supported architectures


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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-lang/mono-2.10.9-r2"
