The vulnerability of the VLC Media Player software allows a malicious attacker to compromise the confidentiality, integrity, and accessibility of protected information.

Overfilling the buffer in the readserverhello function in lib/gnutlshandshake.c in GnuTLS allows remote servers to trigger a service failure a memory-related error or execute arbitrary code using the long session identifier in the ServerHello message...

The vulnerability of the OpenSSL software allows a malicious attacker to compromise the accessibility of protected information.

The vulnerability in the sslsetclientdisabled function in t1lib.c of OpenSSL allows remote SSL servers to trigger a service failure by replacing the null pointer and terminating the client application abnormally, using the ServerHello message. This message includes the SRP crypto packet without...

The vulnerability of the OpenSSL library, which allows attackers to carry out attacks aimed at reducing the security of encryption algorithms

The vulnerability of the OpenSSL library is related to errors in cryptographic transformations. Exploiting this vulnerability allows a malicious actor, operating remotely and having access to the data transmission channel, to carry out attacks aimed at reducing the resilience of encryption...

TLS protocol man-in-the-middle attack vulnerability

TLS Transport Layer Security is a set of protocols used to provide confidentiality and data integrity between two communicating applications. A security vulnerability exists in the TLS protocol version 1.2 and earlier. When the server enabled the DHEEXPORT cipher suite, the program failed to...

CVE-2015-4000

The TLS protocol 1.2 and earlier, when a DHEEXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHEEXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHEEXPORT and then...

OpenSSL TLS Missing SRP Extension Denial of Service (CVE-2014-5139)

A denial of service vulnerability has been reported in OpenSSL. The vulnerability is due to an issue while parsing Server Hello messages with a specific cipher suite and extension. A remote unauthenticated attacker could exploit this vulnerability by sending a specially crafted packet to a target...
