CVE-2010-3477: Canonical Ubuntu Linux

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

The tcf_act_police_dump function in net/sched/act_police.c in the actions implementation in the network queueing functionality in the Linux kernel before 2.6.36-rc4 does not properly initialize certain structure members, which allows local users to obtain potentially sensitive information from kernel memory via vectors involving a dump operation. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-2942.

Affected products

• Canonical Ubuntu Linux: version 6.06 only; version 8.04 only; version 9.04 only; version 9.10 only; version 10.04 only; version 10.10 only
• Debian Debian Linux: version 5.0 only
• Linux Linux Kernel: before 2.6.36 (fixed in 2.6.36); version 2.6.36 only
