CVE-2010-3873

Publication date 3 January 2011

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The X.25 implementation in the Linux kernel before 2.6.36.2 does not properly parse facilities, which allows remote attackers to cause a denial of service (heap memory corruption and panic) or possibly have unspecified other impact via malformed (1) X25_FAC_CALLING_AE or (2) X25_FAC_CALLED_AE data, related to net/x25/x25_facilities.c and net/x25/x25_in.c, a different vulnerability than CVE-2010-4164.

From the Ubuntu Security Team

Dan Rosenberg discovered that the Linux kernel X.25 implementation incorrectly parsed facilities. A remote attacker could exploit this to crash the kernel, leading to a denial of service.
