Vulnerability from variot
racoon/gssapi.c in IPsec-Tools 0.8.2 allows remote attackers to cause a denial of service (NULL pointer dereference and IKE daemon crash) via a series of crafted UDP requests. Supplementary information : CWE Vulnerability type by CWE-476: NULL Pointer Dereference (NULL Pointer dereference ) Has been identified. IPsec-Tools is a user-space implementation of different IPSec. It is ported from KAME's libipsec, setkey and racoon, and supports various BSD systems. A remote attacker could use this vulnerability to cause a program to deny legitimate users. IPsec-Tools is prone to a denial-of-service vulnerability caused by a NULL-pointer dereference error. A security vulnerability exists in the racoon/gssapi.c file of IPsec-Tools version 0.8.2. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512

Supplementary information : CWE Vulnerability type by CWE-476: NULL Pointer Dereference (NULL Pointer dereference ) Has been identified. IPsec-Tools is a user-space implementation of different IPSec. It is ported from KAME\u0027s libipsec, setkey and racoon, and supports various BSD systems. A remote attacker could use this vulnerability to cause a program to deny legitimate users. IPsec-Tools is prone to a denial-of-service vulnerability caused by a NULL-pointer dereference error. A security vulnerability exists in the racoon/gssapi.c file of IPsec-Tools version 0.8.2. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA512\n\n-
