Name of the Vulnerable Software and Affected Versions OMG DDS Security version 1.1 Description The handshake protocol in OMG DDS Security sends cleartext information about all participant capabilities, making it easier for attackers to discover potentially sensitive reachability information on a...

openssl: certificate message OOB reads

Multiple out of bounds read flaws were found in the way OpenSSL handled certain TLS/SSL protocol handshake messages. A remote attacker could possibly use these flaws to crash a TLS/SSL server or client using OpenSSL...

F5 BIG-IP Denial of Service Vulnerability (CNVD-2018-15639)

F5 BIG-IP is a collection of software and hardware that allows you to control the traffic that passes through your network. A denial-of-service vulnerability exists in F5 BIG-IP 11.x, 12.x, and 13.x. A remote attacker could send specially crafted data during the Transport Layer Security TLS...

Fortinet FortiGate < 5.2 / 5.2.x <= 5.2.11 / 5.4.x <= 5.4.5 / 5.6.x <= 5.6.2 Multiple Vulnerabilities (FG-IR-17-196) (KRACK)

The remote host is running FortiOS prior to 5.2, 5.2.x prior to or equal to 5.2.11, 5.4.x prior to or equal 5.4.5, or 5.6.x prior to or equal to 5.6.2. It is, therefore, affected by multiple vulnerabilities discovered in the WPA2 handshake protocol. Note these issues affect only WiFi model device...

Access Bypass

OpenSSL is vulnerable to access bypass. OpenSSL accepts client authentication with a Diffie-Helman certificate without receiving a CertificateValue message. This allows attacks to gain access without the knowledge of a private key via crafted TLS Handshake Protocol traffic to a server that...

The vulnerability of the Dovecot mail server, which allows a remote attacker to cause a service failure

The Dovecot software contains a vulnerability related to unterminated installed sessions. Exploiting these sessions allows a malicious attacker to trigger a service failure by sending specially crafted packets during an SSL/TLS handshake when establishing IMAP/POP3 connections...

TLS 1.2 Transcipt Collision attacks against MD5 in key exchange protocol (SLOTH)

A flaw was found in the way TLS 1.2 could use the MD5 hash function for signing ServerKeyExchange and Client Authentication packets during a TLS handshake. A man-in-the-middle attacker able to force a TLS connection to use the MD5 hash function could use this flaw to conduct collision attacks to...

CVE-2015-5887

The TLS Handshake Protocol implementation in Secure Transport in Apple OS X before 10.11 accepts a Certificate Request message within a session in which no Server Key Exchange message has been sent, which allows remote attackers to have an unspecified impact via crafted TLS data...

CVE-2015-5887

CVE-2015-5887 affects Apple macOS Secure Transport: the TLS Handshake Protocol in OS X before 10.11 accepts a CertificateRequest within a session that did not send ServerKeyExchange. This allows remote attackers to influence the TLS negotiation via crafted data, with an unspecified impact. The is...

Name of the Vulnerable Software and Affected Versions Apple OS X versions prior to 10.11 Description The issue is related to the TLS Handshake Protocol implementation in Secure Transport, which accepts a Certificate Request message within a session where no Server Key Exchange message has been...

CVE-2015-5887: Undefined Security Weakness

The TLS Handshake Protocol implementation in Secure Transport in Apple OS X before 10.11 accepts a Certificate Request message within a session in which no Server Key Exchange message has been sent, which allows remote attackers to have an unspecified impact via crafted TLS data...

SSL/TLS Suffers ‘Bar Mitzvah Attack’vulnerability detection method and repair recommendations-vulnerability warning-the black bar safety net

0x01 introduction April Fool's Day is coming, and SSL again due to the Bar Mitzvah Attack vulnerability to get everyone to not mind. Held in Singapore's Black Hat Asia Security Conference, the Imperva security Director Itsik Mantin detailed description of how to use the attack principle,the...

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...
