More information:

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.
