Stack-based buffer overflow in the is_git_directory function in setup.c in Git before 1.7.2.1 allows local users to gain privileges via a long gitdir: field in a .git file in a working copy.

This update fixes two vulnerabilities :

XSS vulnerability in gitweb; a remote attacker could craft an URL such that arbitrary content would be inserted to the generated web page.

Stack overflow vulnerability that can lead to arbitrary code execution if user runs any git command on a specially crafted git working copy.

Security Issue references :

- [CVE-2010-3906](http://cve.mitre.org/cgi-bin/cvename.cgi?nam e=CVE-2010-3906) 

- [CVE-2010-2542](http://cve.mitre.org/cgi-bin/cvename.cgi?nam e=CVE-2010-2542)

The remote host is affected by the vulnerability described in GLSA-201401-06 (Git: Privilege escalation)

    Git contains a stack-based buffer overflow in the is_git_directory       function in setup.c.
  Impact :

    A local attacker could gain escalated privileges via a specially crafted       git repository.
  Workaround :

    There is no known workaround at this time.

This fixes a security issue where a special crafted .git file could cause arbitrary code execution (CVE-2010-2542).

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A vulnerability has been found and corrected in git :

Stack-based buffer overflow in the is_git_directory function in setup.c in Git before 1.7.2.1 allows local users to gain privileges via a long gitdir: field in a .git file in a working copy (CVE-2010-2542).

The updated packages have been patched to correct this issue.

The Debian stable point release 5.0.6 included updated packages of the Git revision control system in order to fix a security issue.
Unfortunately, the update introduced a regression which could make it impossible to clone or create Git repositories. This upgrade fixes this regression, which is tracked as Debian bug #595728.

The original security issue allowed an attacker to execute arbitrary code if he could trick a local user to execute a git command in a crafted working directory (CVE-2010-2542 ).

Greg Brockman reports :

If an attacker were to create a crafted working copy where the user runs any git command, the attacker could force execution of arbitrary code.
