Description

This security bulletin contains information about 1 vulnerability.


1) Null pointer dereference (CVE-ID: CVE-2006-0036)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


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.
