The name size leads to an arithmetic overflow leading to a zero-size allocation further causing a heap-based buffer overflow with attacker controlled data.

Cherokee 0.4.27 to 1.2.104 is affected by a denial of service due to a NULL pointer dereferences. A remote unauthenticated attacker can crash the server by sending an HTTP request to protected resources using a malformed Authorization header that is mishandled during a cherokee_buffer_add call within cherokee_validator_parse_basic or cherokee_validator_parse_digest.

A vulnerability was found in Wildfly's Enterprise Java Beans (EJB) versions shipped with Red Hat JBoss EAP 7, where SessionOpenInvocations are never removed from the remote InvocationTracker after a response is received in the EJB Client, as well as the server. This flaw allows an attacker to craft a denial of service attack to make the service unavailable.

OpenVPN Access Server older than version 2.8.4 and version 2.9.5 generates new user authentication tokens instead of reusing exiting tokens on reconnect making it possible to circumvent the initial token expiry timestamp.

libldap in certain third-party OpenLDAP packages has a certificate-validation flaw when the third-party package is asserting RFC6125 support. It considers CN even when there is a non-matching subjectAltName (SAN). This is fixed in, for example, openldap-2.4.46-10.el8 in Red Hat Enterprise Linux.

The bubblewrap sandbox of WebKitGTK and WPE WebKit, prior to 2.28.3, failed to properly block access to CLONE_NEWUSER and the TIOCSTI ioctl. CLONE_NEWUSER could potentially be used to confuse xdg-desktop-portal, which allows access outside the sandbox. TIOCSTI can be used to directly execute commands outside the sandbox by writing to the controlling terminal's input buffer, similar to CVE-2017-5226.
