CVE-2011-1180

Published: 25 July 2011

Multiple stack-based buffer overflows in the iriap_getvaluebyclass_indication function in net/irda/iriap.c in the Linux kernel before 2.6.39 allow remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging connectivity to an IrDA infrared network and sending a large integer value for a (1) name length or (2) attribute length.

From the Ubuntu Security Team

Dan Rosenberg discovered that the IRDA subsystem did not correctly check certain field sizes. If a system was using IRDA, a remote attacker could send specially crafted traffic to crash the system or gain root privileges.

Priority

CVSS 3 base score: 9.8
