qpid-proton: TLS Man in the Middle Vulnerability

A cryptographic weakness was discovered in qpid-proton's use of TLS. If the qpid-proton client was used without client certificates, it would accept an anonymous cipher offered by the server. A man-in-the-middle attacker could use this to silently intercept traffic that should have been encrypted...

The vulnerabilities of SIMATIC device software, related to errors in cryptography usage, allow attackers to obtain the TLS session key.

The vulnerability of SIMATIC device software is related to errors in the use of cryptography. Exploiting this vulnerability can allow a perpetrator with access to the web interface to obtain the TLS session key while monitoring the TLS traffic between the legitimate user and the device...

openssl: Malicious server can send large prime to client during DH(E) TLS handshake causing the client to hang

During key agreement in a TLS handshake using a DHE based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This...

DEBIAN-CVE-2019-11873

wolfSSL 4.0.0 has a Buffer Overflow in DoPreSharedKeys in tls13.c when a current identity size is greater than a client identity size. An attacker sends a crafted hello client packet over the network to a TLSv1.3 wolfSSL server. The length fields of the packet: record length, client hello length,...

SSL/TLS: Birthday attack against 64-bit block ciphers (SWEET32)

A flaw was found in the way the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based...

CVE-2019-1833

A vulnerability in the Secure Sockets Layer SSL/Transport Layer Security TLS protocol parser of Cisco Firepower Threat Defense FTD Software could allow an unauthenticated, remote attacker to bypass configured policies. The vulnerability is due to improper parsing of specific attributes in a TLS...

The vulnerability of the network operating system NX-OS for Cisco Nexus 9000 routers is related to errors in verifying the Transport Layer Security (TLS) credentials. This allows a hacker to gain full control over all components within the ACI structure of the vulnerable device.

The vulnerability of the network operating system NX-OS for Cisco Nexus 9000 series routers is related to errors in verifying the authenticity of Transport Layer Security TLS certificates. Exploiting this vulnerability can allow a malicious actor, operating remotely, to gain full control over all...
