Fedora 28 : git (2018-75f7624a9f)

high Nessus Plugin ID 120535
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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/[email protected] .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). ```

A preliminary patch to resolve an issue with zlib on aarch64 is also included (RHBZ#1582555).

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.
