While this is no problem for the daemon itself as every request will spawn a new git-daemon instance, this still results in a very high CPU consumption and might lead to denial of service conditions.
For the oldstable distribution (etch), this problem has been fixed in version 1.4.4.4-4+etch3.
For the stable distribution (lenny), this problem has been fixed in version 1.5.6.5-3+lenny2.
For the testing distribution (squeeze), this problem has been fixed in version 1:1.6.3.3-1.
For the unstable distribution (sid), this problem has been fixed in version 1:1.6.3.3-1.
We recommend that you upgrade your git-core packages.");
