Detail

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.

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"
