It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-default configurations. This could allows attackers with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix this issue by removing support for message lookup patterns and disabling JNDI functionality by default.

Cross-site scripting (XSS) vulnerability in Tor World Tor Search 1.1 and earlier, I-Navigator 4.0, Mobile Frontier 2.1 and earlier, Diary.cgi (aka Quotes of the Day) 1.5 and earlier, Tor News 1.21 and earlier, Simple BBS 1.3 and earlier, Interactive BBS 1.3 and earlier, Tor Board 1.1 and earlier, Simple Vote 1.1 and earlier, and Com Vote 1.2 and earlier allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The POP3 mail client in Mozilla 1.0 and earlier, and Netscape Communicator 4.7 and earlier, allows remote attackers to cause a denial of service (no new mail) via a mail message containing a dot (.) at a newline, which is interpreted as the end of the message.

Mozilla 0.9.6 and earlier and Netscape 6.2 and earlier allows remote attackers to steal cookies from another domain via a link with a hex-encoded null character (%00) followed by the target domain.

By default, Internet Explorer 5.0 and other versions enables the "Navigate sub-frames across different domains" option, which allows frame spoofing.

The byte code verifier component of the Java Virtual Machine (JVM) allows remote execution through malicious web pages.

Internet Explorer 3.x to 4.01 allows a remote attacker to insert malicious content into a frame of another web site, aka frame spoofing.
