Security Bulletin: Log4j Core TLS hostname verification bypass via verifyHostName XML attribute allows man-in-the-middle attacks on SMTP/Socket/Syslog appenders.

Summary Vulnerabilities have been identified in Apache Log4j Core affecting TLS security and log integrity. The first leaves TLS hostname verification silently ineffective through version 2.25.3, exposing SMTP, Socket, and Syslog appenders to man-in-the-middle attacks. The second introduces CRLF...

Security Bulletin: Log4j Core TLS hostname verification bypass via verifyHostName XML attribute allows man-in-the-middle attacks on SMTP/Socket/Syslog appenders.

Summary Vulnerabilities have been identified in Apache Log4j Core versions up to 2.25.3 affecting TLS security, log integrity, and XML output handling. The first exposes SMTP, Socket, and Syslog appenders to man-in-the-middle attacks due to silently ineffective hostname verification; the second...

RUSTSEC-2026-0194 Quadratic run time when checking a start tag for duplicate attribute names

BytesStart::attributes returns an Attributes iterator which, by default withcheckstrue, rejects a start tag that repeats an attribute name. For each attribute yielded, the iterator compared the new name against every name seen so far in the same tag using a linear scan, so a start tag with N...
