The FTP server in the NEC MultiWriter 1700C allows remote attackers to redirect traffic to other sites (aka FTP bounce) via the PORT command, a variant of CVE-1999-0017.
The Internet Key Exchange version 1 (IKEv1) implementation in NEC UNIVERGE IX1000, IX2000, and IX3000 allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to.
Multiple buffer overflows in NEC SOCKS5 1.0 r11 and earlier allow remote attackers to cause a denial of service and possibly execute arbitrary code via a long username to (1) the GetString function in proxy.c for the SOCKS5 module or (2) the HandleS4Connection function in proxy.c for the SOCKS4 module.
IPSEC implementations including (1) FreeS/WAN and (2) KAME do not properly calculate the length of authentication data, which allows remote attackers to cause a denial of service (kernel panic) via spoofed, short Encapsulating Security Payload (ESP) packets, which result in integer signedness errors.
