Linux Distros Unpatched Vulnerability : CVE-2024-45775

medium Nessus Plugin ID 229155

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 flaw was found in grub2 where the grub_extcmd_dispatcher() function calls grub_arg_list_alloc() to allocate memory for the grub's argument list. However, it fails to check in case the memory allocation fails. Once the allocation fails, a NULL point will be processed by the parse_option() function, leading grub to crash or, in some rare scenarios, corrupt the IVT data. (CVE-2024-45775)

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

Solution

There is no known solution at this time.
