CVE-2006-4521

The BerDecodeLoginDataRequest function in the libnmasldap.so NMAS module in Novell eDirectory 8.8 and 8.8.1 before the Security Services 2.0.3 patch does not properly increment a pointer when handling certain input, which allows remote attackers to cause a denial of service (invalid memory access) via a crafted login request.
