Synopsis
========
An error in git-daemon might lead to a Denial of Service via resource
consumption.
Background
==========
git - the stupid content tracker, the revision control system used by
the Linux kernel team.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-util/git < 1.6.3.3 >= 1.6.3.3
Description
===========
Shawn O. Pearce reported that git-daemon runs into an infinite loop
when handling requests that contain unrecognized arguments.
Impact
======
A remote unauthenticated attacker could send a specially crafted
request to git-daemon, possibly leading to a Denial of Service (CPU
consumption).
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All git users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-util/git-1.6.3.3"
