git - the stupid content tracker, the revision control system used by the Linux kernel team.
Shawn O. Pearce reported that git-daemon runs into an infinite loop when handling requests that contain unrecognized arguments.
A remote unauthenticated attacker could send a specially crafted request to git-daemon, possibly leading to a Denial of Service (CPU consumption).
There is no known workaround at this time.
All git users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-util/git-18.104.22.168"
