Linux Distros Unpatched Vulnerability : CVE-2024-45779

medium Nessus Plugin ID 232150

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 integer overflow flaw was found in the BFS file system driver in grub2. When reading a file with an indirect extent map, grub2 fails to validate the number of extent entries to be read. A crafted or corrupted BFS filesystem may cause an integer overflow during the file reading, leading to a heap of bounds read. As a consequence, sensitive data may be leaked, or grub2 will crash. (CVE-2024-45779)

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

Solution

There is no known solution at this time.
