Description
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The pipe_fcntl function in fs/pipe.c in the Linux kernel before 2.6.37 does not properly determine whether a file is a named pipe, which allows local users to cause a denial of service via an F_SETPIPE_SZ fcntl call.
