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...

OpenJDK: incorrect tracking of ChangeCipherSpec during SSL/TLS handshake (JSSE, 8057555)

It was discovered that the SSL/TLS implementation in the JSSE component in OpenJDK failed to properly check whether the ChangeCipherSpec was received during the SSL/TLS connection handshake. An MITM attacker could possibly use this flaw to force a connection to be established without encryption...

Wireshark TLS/SSL Decryption Denial of Service Vulnerability

Wireshark is an open source network protocol analysis tool. A denial of service vulnerability exists in Wireshark TLS/SSL because it fails to properly handle certain types of packets. An attacker could exploit this vulnerability to crash the affected application and deny service to legitimate use...

OpenJDK: Triple Handshake attack against TLS/SSL connections (JSSE, 8037066)

It was discovered that the TLS/SSL implementation in the JSSE component in OpenJDK failed to properly verify the server identity during the renegotiation following session resumption, making it possible for malicious TLS/SSL servers to perform a Triple Handshake attack against clients using JSSE...

SSL/TLS: Padding Oracle On Downgraded Legacy Encryption attack

A flaw was found in the way SSL 3.0 handled padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining CBC mode. This flaw allows a man-in-the-middle MITM attacker to decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a...

Google Releases 'nogotofail' Network Traffic Security Testing Tool

Google introduced a new security tool to help developers detect bugs and security glitches in the network traffic security that may leave passwords and other sensitive information open to snooping. The open source tool, dubbed as Nogotofail, has been launched by the technology giant in sake of a...

Google Releases Nogotofail Tool to Test Network Security

The last year has produced a rogues’ gallery of vulnerabilities in transport layer security implementations and new attacks on the key protocols, from Heartbleed to the Apple gotofail flaw to the recent POODLE attack. To help developers and security researchers identify applications that are...

PT-2015-1696

Name of the Vulnerable Software and Affected Versions TLS protocol versions 1.2 and earlier Description The issue concerns a problem with the TLS protocol where a DHE EXPORT ciphersuite is enabled on a server but not on a client, allowing man-in-the-middle attackers to conduct cipher-downgrade...

openssl: SRTP memory leak causes crash when using specially-crafted handshake message

A memory leak flaw was found in the way OpenSSL parsed the DTLS Secure Real-time Transport Protocol SRTP extension data. A remote attacker could send multiple specially crafted handshake messages to exhaust all available memory of an SSL/TLS or DTLS server...
