How to fix?

Upgrade Ubuntu:16.04 git to version 1:2.7.4-0ubuntu1.10+esm5 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream git package and not the git package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

Git, a revision control system, is vulnerable to path traversal prior to versions 2.39.2, 2.38.4, 2.37.6, 2.36.5, 2.35.7, 2.34.7, 2.33.7, 2.32.6, 2.31.7, and 2.30.8. By feeding a crafted input to git apply, a path outside the working tree can be overwritten as the user who is running git apply. A fix has been prepared and will appear in v2.39.2, v2.38.4, v2.37.6, v2.36.5, v2.35.7, v2.34.7, v2.33.7, v2.32.6, v2.31.7, and v2.30.8. As a workaround, use git apply --stat to inspect a patch before applying; avoid applying one that creates a symbolic link and then creates a file beyond the symbolic link.
