Linux Distros Unpatched Vulnerability : CVE-2017-17458

critical Nessus Plugin ID 221149

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - In Mercurial before 4.4.1, it is possible that a specially malformed repository can cause Git subrepositories to run arbitrary code in the form of a .git/hooks/post-update script checked into the repository. Typical use of Mercurial prevents construction of such repositories, but they can be created programmatically. (CVE-2017-17458)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
