    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.

    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
    vulnerabilitiy 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.
