Linux Distros Unpatched Vulnerability : CVE-2024-45776

medium Nessus Plugin ID 229005

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.

 - When reading the language .mo file in grub_mofile_open(), grub2 fails to verify an integer overflow when allocating its internal buffer. A crafted .mo file may lead the buffer size calculation to overflow, leading to out-of-bound reads and writes. This flaw allows an attacker to leak sensitive data or overwrite critical data, possibly circumventing secure boot protections. (CVE-2024-45776)

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

Solution

There is no known solution at this time.
