SynopsisThe remote Fedora host is missing a security update.
DescriptionUpstream security update resolving an issue with `git clone
From the [upstream release announcement](https://public-inbox.org/git/[email protected] .c.googlers.com/) :
> These releases fix a security flaw (CVE-2018-17456), which allowed an > attacker to execute arbitrary code by crafting a malicious .gitmodules > file in a project cloned with --recurse-submodules. > > When running 'git clone --recurse-submodules', Git parses the supplied > .gitmodules file for a URL field and blindly passes it as an argument > to a 'git clone' subprocess. If the URL field is set to a string that > begins with a dash, this 'git clone' subprocess interprets the URL as > an option. This can lead to executing an arbitrary script shipped in > the superproject as the user who ran 'git clone'. > > In addition to fixing the security issue for the user running 'clone', > the 2.17.2, 2.18.1 and 2.19.1 releases have an 'fsck' check which can > be used to detect such malicious repository content when fetching or > accepting a push. See 'transfer.fsckObjects' in git-config(1). > > Credit for finding and fixing this vulnerability goes to joernchen > and Jeff King, respectively.
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.
SolutionUpdate the affected git package.
