Synopsis

The remote Fedora host is missing a security update.

Description

Upstream security fixes related to .gitmodules handling. From the [upstream announcement](https://public-inbox.org/git/xmqqy3g2flb6.fsf@gitster-ct .c.googlers.com/) :

```

 - Submodule 'names' come from the untrusted .gitmodules file, but we blindly append them to $GIT_DIR/modules to create our on-disk repo paths. This means you can do bad things by putting '../' into the name. We now enforce some rules for submodule names which will cause Git to ignore these malicious names (CVE-2018-11235).

 Credit for finding this vulnerability and the proof of concept from which the test script was adapted goes to Etienne Stalmans.

 - It was possible to trick the code that sanity-checks paths on NTFS into reading random piece of memory (CVE-2018-11233). ```

Also fix a segfault in rev-parse with invalid input (#1581678) and install contrib/diff-highlight (#1550251).

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.
