Multiple use-after-free vulnerabilities in the (1) htmlPArsePubidLiteral and (2) htmlParseSystemiteral functions in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allow remote attackers to cause a denial of service via a crafted XML document.

Use-after-free vulnerability in the xmlDictComputeFastKey function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to cause a denial of service via a crafted XML document.

Heap-based buffer overflow in the xmlStrncat function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document.

The xmlNextChar function in libxml2 before 2.9.4 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted XML document.

win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP1 and SP2, Windows Server 2008 Gold, SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 allows local users to gain privileges via a crafted application that triggers a NULL pointer dereference, a different vulnerability than other "Vulnerability Type 2" CVEs listed in MS11-034, aka "Win32k Null Pointer De-reference Vulnerability."

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.

Unspecified vulnerability in Sun ONE (aka iPlanet) Web Server 6.0 SP3 through SP5 on Windows allows remote 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.

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.
