OpenSSL DTLS Handshake Memory Exhaustion (CVE-2014-3506)

A denial of service vulnerability exists in OpenSSL. The vulnerability is due to large memory consumption during reassembly of the fragmented DTLS handshake. A remote, unauthenticated attacker could exploit this vulnerability by sending specially crafted messages to a target...

openssl: DTLS anonymous (EC)DH denial of service

A NULL pointer dereference flaw was found in the way OpenSSL performed a handshake when using the anonymous Diffie-Hellman DH key exchange. A malicious server could cause a DTLS client using OpenSSL to crash if that client had anonymous DH cipher suites enabled...

openssl: DoS when sending invalid DTLS handshake

A denial of service flaw was found in the way OpenSSL handled certain DTLS ServerHello requests. A specially crafted DTLS handshake packet could cause a DTLS client using OpenSSL to crash...

Scientific Linux Security Update : openssl on SL5.x i386/x86_64 (20140813)

It was discovered that the OBJobj2txt function could fail to properly NUL-terminate its output. This could possibly cause an application using OpenSSL functions to format fields of X.509 certificates to disclose portions of its memory. CVE-2014-3508 Multiple flaws were discovered in the way OpenS...

Scientific Linux Security Update : openssl on SL6.x i386/x86_64 (20140813)

A race condition was found in the way OpenSSL handled ServerHello messages with an included Supported EC Point Format extension. A malicious server could possibly use this flaw to cause a multi-threaded TLS/SSL client using OpenSSL to write into freed memory, causing the client to crash or execut...

openssl: DTLS anonymous (EC)DH denial of service

A NULL pointer dereference flaw was found in the way OpenSSL performed a handshake when using the anonymous Diffie-Hellman DH key exchange. A malicious server could cause a DTLS client using OpenSSL to crash if that client had anonymous DH cipher suites enabled...

openssl: TLS protocol downgrade attack

A flaw was found in the way OpenSSL handled fragmented handshake packets. A man-in-the-middle attacker could use this flaw to force a TLS/SSL server using OpenSSL to use TLS 1.0, even if both the client and the server supported newer protocol versions...

OpenSSL 'ChangeCipherSpec' MiTM Vulnerability

The OpenSSL service on the remote host is vulnerable to a man-in-the-middle MiTM attack, based on its acceptance of a specially crafted handshake. This flaw could allow a MiTM attacker to decrypt or forge SSL messages by telling the service to begin encrypted communications before key material ha...

CVE-2014-3510

The ssl3sendclientkeyexchange function in s3clnt.c in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i allows remote DTLS servers to cause a denial of service NULL pointer dereference and client application crash via a crafted handshake message in conjunction with a 1...
