CVE-2011-4914

Published: 4 January 2012

The ROSE protocol implementation in the Linux kernel before 2.6.39 does not verify that certain data-length values are consistent with the amount of data sent, which might allow remote attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read) via crafted data to a ROSE socket.

From the Ubuntu Security Team

Ben Hutchings discovered several flaws in the Linux Rose (X.25 PLP) layer. A local user or a remote user on an X.25 network could exploit these flaws to execute arbitrary code as root.
