Description Marcel Holtmann 2007-06-08 06:20:19 EDT
A vulnerability has been reported in the Linux Kernel, which potentially can be
exploited by malicious, local users to cause a DoS (Denial of Service).

The vulnerability is caused due to a memory leak when releasing PPPoE sockets
after they are connected, but before the "PPPIOCGCHAN" ioctl is called. This can
be exploited to cause a DoS due to memory exhaustion.
