CVE-2010-4164

Published: 03 January 2011

Multiple integer underflows in the x25_parse_facilities function in net/x25/x25_facilities.c in the Linux kernel before 2.6.36.2 allow remote attackers to cause a denial of service (system crash) via malformed X.25 (1) X25_FAC_CLASS_A, (2) X25_FAC_CLASS_B, (3) X25_FAC_CLASS_C, or (4) X25_FAC_CLASS_D facility data, a different vulnerability than CVE-2010-3873.

From the Ubuntu security team

Dan Rosenberg discovered multiple flaws in the X.25 facilities parsing. If a system was using X.25, a remote attacker could exploit this to crash the system, leading to a denial of service.
