Doc Text: |
An out-of-bounds flaw was found in the kernel, where the length of the sockaddr parameter was not checked in the pptp_bind() and pptp_connect() functions. As a result, more kernel memory was copied out than required, leaking information from the kernel stack (including kernel addresses). A local system user could exploit this flaw to bypass kernel ASLR or leak other information.
