Package        : git-core
Vulnerability  : shell command injection
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2008-5516 CVE-2008-5517
Debian Bug     : 512330

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-2008-5516).

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-2008-5517).

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 issuei (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.
