Linux Kernel dccp_feat_change() buffer overflow
|linux-kernel-dccpfeatchange-bo (43034)||High Risk|
Linux Kernel is vulnerable to a buffer overflow, caused by improper bounds checking by the dccp_feat_change() function within the Datagram Congestion Control Protocol (DCCP) subsystem. By sending a specially-crafted request, a local attacker could overflow a buffer and execute arbitrary code on the system with kernel privileges or cause the application to crash.
Upgrade to the latest version of Linux Kernel (22.214.171.124 or later), available from The Linux Kernel Archives Web site. See References.
For other distributions:
Apply the appropriate update for your system. See References.
