Linux Distros Unpatched Vulnerability : CVE-2024-45781

medium Nessus Plugin ID 228486

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 grub2. When reading a symbolic link's name from a UFS filesystem, grub2 fails to validate the string length taken as an input. The lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and eventually allowing an attacker to circumvent secure boot protections. (CVE-2024-45781)

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

Solution

There is no known solution at this time.
