Unspecified vulnerability in Sun ONE (aka iPlanet) Web Server 4.1 before SP13 and 6.0 before SP6 on Windows allows attackers to cause a denial of service (daemon crash) via unknown vectors.

Sun ONE (aka iPlanet) Web Server 4.1 through SP12 and 6.0 through SP5, when DNS resolution is enabled for client IP addresses, allows remote attackers to hide HTTP requests from the log-preview functionality by accompanying the requests with crafted DNS responses specifying a domain name beginning with a "format=" substring, related to an "Inverse Lookup Log Corruption (ILLC)" issue.

Sun ONE (aka iPlanet) Web Server 4.1 through SP12 and 6.0 through SP5, when DNS resolution is enabled for client IP addresses, allows remote attackers to inject arbitrary text into log files, and conduct cross-site scripting (XSS) attacks involving the iPlanet Log Analyzer, via an HTTP request in conjunction with a crafted DNS response, related to an "Inverse Lookup Log Corruption (ILLC)" issue, a different vulnerability than CVE-2002-1315 and CVE-2002-1316.

The default configuration of Sun ONE/iPlanet Web Server 4.1 SP1 through SP12 and 6.0 SP1 through SP5 responds to the HTTP TRACE request, which can allow remote attackers to steal information using cross-site tracing (XST) attacks in applications that are vulnerable to cross-site scripting.

Heap-based buffer overflow in Netscape Network Security Services (NSS) library allows remote attackers to execute arbitrary code via a modified record length field in an SSLv2 client hello message.
