Linux Distros Unpatched Vulnerability : CVE-2017-7501

high Nessus Plugin ID 221756

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.

- It was found that versions of rpm before 4.13.0.2 use temporary files with predictable names when installing an RPM. An attacker with ability to write in a directory where files will be installed could create symbolic links to an arbitrary location and modify content, and possibly permissions to arbitrary files, which could be used for denial of service or possibly privilege escalation. (CVE-2017-7501)

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

Solution

There is no known solution at this time.
