Severity:	normal
Title:	Git: Multiple vulnerabilities
Date:	05/02/2016
Bugs:	#562884, #577482
ID:	201605-01

Synopsis

Git contains multiple vulnerabilities that allow for the remote execution of arbitrary code.

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.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-vcs/git	< 2.7.3-r1	>= 2.7.3-r1	All supported architectures

Description

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.

Resolution

All Git users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-vcs/git-2.7.3-r1"
