CVE-2010-0307: Canonical Ubuntu Linux

Medium severity, CVSS 4.7. EPSS: 0.8% chance of exploitation in the next 30 days.

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: version 6.06 only; version 8.04 only; version 8.10 only; version 9.04 only; version 9.10 only
• Debian Debian Linux: version 4.0 only; version 5.0 only
• Linux Linux Kernel: before 2.6.32.8 (fixed in 2.6.32.8)
