CVE-2007-2875: Canonical Ubuntu Linux

Low severity, CVSS 2.1. EPSS: 0.4% chance of exploitation in the next 30 days.

Integer underflow in the cpuset_tasks_read function in the Linux kernel before 2.6.20.13, and 2.6.21.x before 2.6.21.4, when the cpuset filesystem is mounted, allows local users to obtain kernel memory contents by using a large offset when reading the /dev/cpuset/tasks file.

Affected products

• Canonical Ubuntu Linux: version 6.06 only; version 6.10 only; version 7.04 only
• Debian Debian Linux: version 3.1 only
• Linux Linux Kernel: before 2.6.20.13 (fixed in 2.6.20.13); from 2.6.21, before 2.6.21.4 (fixed in 2.6.21.4)
