Detail

Synopsis

A stack-based buffer overflow in Git might allow a local attacker to gain escalated privileges.

Background

Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

Description

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.

Resolution

All Git users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-vcs/git-1.7.2.2"

NOTE: This is a legacy GLSA. Updates for all affected architectures are available since September 11, 2010. It is likely that your system is already no longer affected by this issue.

Title: DSA-2114-1 git-core -- buffer overflow
Description: 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. For the stable distribution, this problem has been fixed in version 1.5.6.5-3+lenny3.2. The packages for the hppa architecture are not included in this advisory. However, the hppa architecture is not known to be affected by the regression. For the testing distribution and the unstable distribution, the security issue has been fixed in version 1.7.1-1.1. These distributions were not affected by the regression. We recommend that you upgrade your git-core packages.
