Linux Distros Unpatched Vulnerability : CVE-2022-48337

critical Nessus Plugin ID 225292

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.

 - GNU Emacs through 28.2 allows attackers to execute commands via shell metacharacters in the name of a source-code file, because lib-src/etags.c uses the system C library function in its implementation of the etags program. For example, a victim may use the etags -u * command (suggested in the etags documentation) in a situation where the current working directory has contents that depend on untrusted input. (CVE-2022-48337)

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

Solution

There is no known solution at this time.
