Description
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
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.
Mitigation
Install update from vendor's website.
Vulnerable software versions
Linux kernel: 2.6.0 - 2.6.38.8
