CVE-2010-4342

Publication date 30 December 2010

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The aun_incoming function in net/econet/af_econet.c in the Linux kernel before 2.6.37-rc6, when Econet is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by sending an Acorn Universal Networking (AUN) packet over UDP.

From the Ubuntu Security Team

Nelson Elhage discovered that Econet did not correctly handle AUN packets over UDP. A local attacker could send specially crafted traffic to crash the system, leading to a denial of service.
