An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).

CODESYS V3 web server before 3.5.15.40, as used in CODESYS Control runtime systems, has a buffer overflow.

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.

An unauthenticated remote attacker can causes the CODESYS web server to access invalid memory which results in a DoS.

Improper privilege management in Jungo WinDriver 6.0.0 through 16.1.0 allows local attackers to escalate privileges and execute arbitrary code.

Improper privilege management in Jungo WinDriver before 12.5.1 allows local attackers to escalate privileges and execute arbitrary code.

Denial of Service (DoS) vulnerability in Jungo WinDriver before 12.7.0 allows local attackers to cause a Windows blue screen error.

Improper privilege management in Jungo WinDriver before 12.2.0 allows local attackers to escalate privileges and execute arbitrary code.

Improper privilege management in Jungo WinDriver before 12.5.1 allows local attackers to escalate privileges, execute arbitrary code, or cause a Denial of Service (DoS).

Denial of Service (DoS) vulnerability in Jungo WinDriver before 12.5.1 allows local attackers to cause a Windows blue screen error.
