DSA-1708-1 git-core -- shell command injection

Date Reported:

19 Jan 2009

Affected Packages:

git-core

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 512330.
In Mitre's CVE dictionary: CVE-2008-5516, CVE-2008-5517, CVE-2008-5916.

More information:

It was discovered that gitweb, the web interface for the Git version control system, contained several vulnerabilities:

Remote attackers could use crafted requests to execute shell commands on the web server, using the snapshot generation and pickaxe search functionality (CVE-2008-5916).

Local users with write access to the configuration of a Git repository served by gitweb could cause gitweb to execute arbitrary shell commands with the permission of the web server (CVE-2008-5516, CVE-2008-5517).

For the stable distribution (etch), these problems have been fixed in version 1.4.4.4-4+etch1.

For the unstable distribution (sid) and testing distribution (lenny), the remote shell command injection issue (CVE-2008-5516) has been fixed in version 1.5.6-1. The other issue will be fixed soon.

We recommend that you upgrade your Git packages.

Fixed in:

Debian GNU/Linux 4.0 (etch)
