CVE-2011-1173

Published: 22 June 2011

The econet_sendmsg function in net/econet/af_econet.c in the Linux kernel before 2.6.39 on the x86_64 platform allows remote attackers to obtain potentially sensitive information from kernel stack memory by reading uninitialized data in the ah field of an Acorn Universal Networking (AUN) packet.

From the Ubuntu Security Team

Vasiliy Kulikov discovered that the Acorn Universal Networking driver did not correctly initialize memory. A remote attacker could send specially crafted traffic to read kernel stack memory, leading to a loss of privacy.
