CVE-2010-4160

Publication date 7 January 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

Multiple integer overflows in the (1) pppol2tp_sendmsg function in net/l2tp/l2tp_ppp.c, and the (2) l2tp_ip_sendmsg function in net/l2tp/l2tp_ip.c, in the PPPoL2TP and IPoL2TP implementations in the Linux kernel before 2.6.36.2 allow local users to cause a denial of service (heap memory corruption and panic) or possibly gain privileges via a crafted sendto call.

From the Ubuntu Security Team

Dan Rosenberg discovered that the Linux kernel L2TP implementation contained multiple integer signedness errors. A local attacker could exploit this to to crash the kernel, or possibly gain root privileges.
