Overview

CVE-2010-0307 is a medium-severity vulnerability affecting linux linux_kernel. It was published on February 17, 2010 and has a CVSS 2.0 base score of 4.7 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 4.7, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

The load_elf_binary function in fs/binfmt_elf.c in the Linux kernel before 2.6.32.8 on the x86_64 platform does not ensure that the ELF interpreter is available before a call to the SET_PERSONALITY macro, which allows local users to cause a denial of service (system crash) via a 32-bit application that attempts to execute a 64-bit application and then triggers a segmentation fault, as demonstrated by amd64_killer, related to the flush_old_exec function.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
