Synopsis
========

Heartbeat is vulnerable to symlink attacks, potentially allowing a
local user to overwrite arbitrary files.

Background
==========

Heartbeat is a component of the High-Availability Linux project. It it
used to perform death-of-node detection, communications and cluster
management.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-cluster/heartbeat < 1.2.3-r1 >= 1.2.3-r1

Description
===========

Eric Romang has discovered that Heartbeat insecurely creates temporary
files with predictable filenames.

Impact
======

A local attacker could create symbolic links in the temporary file
directory, pointing to a valid file somewhere on the filesystem. When a
vulnerable script is executed, this could lead to the file being
overwritten with the rights of the user running the affected
application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Heartbeat users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-cluster/heartbeat-1.2.3-r1"
