Description
This security bulletin contains information about 1 security vulnerability.
1) Null pointer dereference (CVE-ID: CVE-2006-0036)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
ip_nat_pptp in the PPTP NAT helper (netfilter/ip_nat_helper_pptp.c) in Linux kernel 2.6.14, and other versions, allows remote attackers to cause a denial of service (memory corruption or crash) via an inbound PPTP_IN_CALL_REQUEST packet that causes a null pointer to be used in an offset calculation.
