Linux Distros Unpatched Vulnerability : CVE-2026-54231

medium Nessus Plugin ID 320967

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 content injection vulnerability was found in the ABRT post-create event handler scripts in libreport.
The event script queries the systemd journal for log entries matching the crashed process and writes the results to files in the dump directory without sanitizing embedded control characters. A local user can inject arbitrary content into the journal output by embedding newline characters in syslog messages, controlling the content that root writes to dump directory files. (CVE-2026-54231)

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

Solution

There is no known solution at this time.
