TITLE:
GIT "gitweb" Command Injection Vulnerabilities

SECUNIA ADVISORY ID:
SA33607

VERIFY ADVISORY:
http://secunia.com/advisories/33607/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
GIT 1.x
http://secunia.com/advisories/product/7172/

DESCRIPTION:
Some vulnerabilities have been reported in GIT, which can be
exploited by malicious people to potentially compromise a vulnerable
system.

The vulnerabilities are caused due to the "git_search()",
"git_cmd()", "git_snapshot()", and "git_object()" functions in
gitweb/gitweb.pl not properly sanitising certain parameters before
using them in a call to e.g. "open()", which can be exploited to
inject and execute arbitrary shell commands by sending specially
crafted requests to the interface.

SOLUTION:
Update to version 1.5.6.6 or 1.6.1.
