GLSA-201605-01 : Git: Multiple vulnerabilities

critical Nessus Plugin ID 90849

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201605-01 (Git: Multiple vulnerabilities)

 Git is vulnerable to the remote execution of arbitrary code by cloning repositories with large filenames or a large number of nested trees.
 Additionally, some protocols within Git, such as git-remote-ext, can execute arbitrary code found within URLs. These URLs that submodules use may come from arbitrary sources (e.g., .gitmodules files in a remote repository), and can effect those who enable recursive fetch. Restrict the allowed protocols to well known and safe ones.
 Impact :

 Remote attackers could execute arbitrary code on both client and server.
 Workaround :

 There is no known workaround at this time.

Solution

All Git users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=dev-vcs/git-2.7.3-r1'
