Linux Distros Unpatched Vulnerability : CVE-2023-1386

high Nessus Plugin ID 232118

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.

- A flaw was found in the 9p passthrough filesystem (9pfs) implementation in QEMU. When a local user in the guest writes an executable file with SUID or SGID, none of these privileged bits are correctly dropped. As a result, in rare circumstances, this flaw could be used by malicious users in the guest to elevate their privileges within the guest and help a host local user to elevate privileges on the host. (CVE-2023-1386)

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

Solution

There is no known solution at this time.
