git-core - buffer overflow

Multiple vulnerabilities have been identified in git-core, the core of
the git distributed revision control system. Improper path length
limitations in git’s diff and grep functions, in combination with
maliciously crafted repositories or changes, could enable a stack
buffer overflow and potentially the execution of arbitrary code.

The Common Vulnerabilities and Exposures project identifies this
vulnerability as CVE-2008-3546.

For the stable distribution (etch), this problem has been fixed in
version 1.4.4.4-2.1+etch1.

For the unstable distribution (sid), this problem has been fixed in
version 1.5.6.5-1.

We recommend that you upgrade your git-core packages.
