CVE-2006-0036

High
Published: Translated: NVD NIST

Summary

In the PPTP NAT helper module of the Linux kernel 2.6.14 and other versions, the ip_nat_pptp function in netfilter/ip_nat_helper_pptp.c allows remote attackers to cause a denial of service (memory corruption or crash) by sending a PPTP_IN_CALL_REQUEST packet that leads to a null pointer being used in an offset calculation.

Risk Assessment

An attacker can remotely crash the system or corrupt memory, leading to disruption of network services and potential data loss.

Recommendation

Immediately update the Linux kernel to a patched version (e.g., 2.6.15 or later) or apply the appropriate security patch provided by your distribution.
