Language:

Synopsis

The remote Fedora host is missing a security update.

Description

Resolve an arbitrary code execution vulnerability via crafted 'ssh://' URL (CVE-2017-1000117).

From the [release announcement](https://public-inbox.org/git/[email protected] v.corp.google.com/) :

A malicious third-party can give a crafted 'ssh://...' URL to an unsuspecting victim, and an attempt to visit the URL can result in any program that exists on the victim's machine being executed. Such a URL could be placed in the .gitmodules file of a malicious project, and an unsuspecting victim could be tricked into running 'git clone
--recurse-submodules' to trigger the vulnerability.

Credits to find and fix the issue go to Brian Neel at GitLab, Joern Schneeweisz of Recurity Labs and Jeff King at GitHub.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected git package.
