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.

Affected products

• Canonical Ubuntu Linux: 6.06, 8.04, 8.10, 9.04, 9.10
• Debian Linux: 4.0, 5.0
• Linux kernel: before 2.6.32.8 — fixed in 2.6.32.8

How to fix

Upgrade to a fixed version: Linux kernel 2.6.32.8. Check the vendor advisory for mitigations.
