gnutls: gnutls: Certificate validation bypass due to oversized Subject Alternative Name
A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name SAN could cause the validation process to incorrectly fall back to checking the Common Name CN field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to...
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...
gnutls: gnutls: Security bypass due to incorrect name constraint handling
A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities CAs only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate...

ROS-20260626-73-0042
The vulnerability of the ngxhttpscgimodule and ngxhttpuwsgimodule modules in NGINX Plus and NGINX Open Source web servers is related to uncontrolled memory consumption. Exploiting this vulnerability can allow a malicious actor to perform a “man-in-the-middle” attack remotely...
CVE-2025-15661
A flaw in libssh2's sftpsymlink function allows a malicious SSH server or man-in-the-middle attacker to trigger an out-of-bounds heap read via a crafted SSHFXPNAME response. This can disclose heap memory contents or crash the application, causing a denial of service DoS. Mitigation Implement stri...
