CVE-2011-1493

Published: 25 July 2011

Array index error in the rose_parse_national function in net/rose/rose_subr.c in the Linux kernel before 2.6.39 allows remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact by composing FAC_NATIONAL_DIGIS data that specifies a large number of digipeaters, and then sending this data to a ROSE socket.

From the Ubuntu Security Team

Dan Rosenberg discovered that the X.25 Rose network stack did not correctly handle certain fields. If a system was running with Rose enabled, a remote attacker could send specially crafted traffic to gain root privileges.
