Linux Distros Unpatched Vulnerability : CVE-2022-48338

high Nessus Plugin ID 225196

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.

 - An issue was discovered in GNU Emacs through 28.2. In ruby-mode.el, the ruby-find-library-file function has a local command injection vulnerability. The ruby-find-library-file function is an interactive function, and bound to C-c C-f. Inside the function, the external command gem is called through shell- command-to-string, but the feature-name parameters are not escaped. Thus, malicious Ruby source files may cause commands to be executed. (CVE-2022-48338)

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

Solution

There is no known solution at this time.
