CVE-2010-1187: Canonical Ubuntu Linux

Medium severity, CVSS 4.9. EPSS: 0.4% chance of exploitation in the next 30 days.

The Transparent Inter-Process Communication (TIPC) functionality in Linux kernel 2.6.16-rc1 through 2.6.33, and possibly other versions, allows local users to cause a denial of service (kernel OOPS) by sending datagrams through AF_TIPC before entering network mode, which triggers a NULL pointer dereference.

Affected products

• Canonical Ubuntu Linux: version 12.04 only
• Debian Debian Linux: version 5.0 only
• Linux Linux Kernel: after 2.6.16, up to and including 2.6.33; version 2.6.16 only
