EulerOS Virtualization 2.5.1 : git (EulerOS-SA-2018-1377)

high Nessus Plugin ID 119068

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the git package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- A flaw was found in the way git-shell handled command-line options for the restricted set of git-shell commands. A remote, authenticated attacker could use this flaw to bypass git-shell restrictions, to view and manipulate files, by abusing the instance of the less command launched using crafted command-line options.(CVE-2017-8386)

- In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x before 2.15.2, 2.16.x before 2.16.4, and 2.17.x before 2.17.1, remote code execution can occur. With a crafted .gitmodules file, a malicious project can execute an arbitrary script on a machine that runs 'git clone
--recurse-submodules' because submodule 'names' are obtained from this file, and then appended to $GIT_DIR/modules, leading to directory traversal with '../' in a name. Finally, post-checkout hooks from a submodule are executed, bypassing the intended design in which hooks are not obtained from a remote server.(CVE-2018-11235)

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

Solution

Update the affected git packages.
