Linux Distros Unpatched Vulnerability : CVE-2024-56803

medium Nessus Plugin ID 326394

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.

 - Ghostty is a cross-platform terminal emulator. Ghostty, as allowed by default in 1.0.0, allows attackers to modify the window title via a certain character escape sequence and then insert it back to the command line in the user's terminal, e.g. when the user views a file containing the malicious sequence, which could allow the attacker to execute arbitrary commands. This attack requires an attacker to send malicious escape sequences followed by convincing the user to physically press the enter key. Fixed in Ghostty v1.0.1. (CVE-2024-56803)

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

Solution

There is no known solution at this time.
