Debian 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.

Package        : git-core
Vulnerability  : buffer overflow
Problem type   : local (remote)
Debian-specific: no
CVE Id(s)      : CVE-2008-3546
Debian Bug     : 494097

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.

We recommend that you upgrade your git-core packages.

Upgrade instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
