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 6 on Windows, when DNS resolution is enabled for client IP addresses, uses a logging format that does not identify whether a dotted quad represents an unresolved IP address, which allows remote attackers to spoof IP addresses via crafted DNS responses containing numerical top-level domains, as demonstrated by a forged 123.123.123.123 domain name, 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 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.

Cross-site scripting (XSS) vulnerability in Sun ONE Web Server 6.0 SP9 and earlier, Java System Web Server 6.1 SP4 and earlier, Sun ONE Application Server 7 Platform and Standard Edition Update 6 and earlier, and Java System Application Server 7 2004Q2 Standard and Enterprise Edition Update 2 and earlier, allows remote attackers to inject arbitrary web script or HTML via unknown attack vectors, possibly involving error messages.
