gnutls: timing side-channel in the TLS RSA key exchange code

A timing side-channel vulnerability was found in RSA ClientKeyExchange messages in GnuTLS. This side-channel may be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption, the attacker would need to send ...

Denial of Service Vulnerability in Multiple EMC RSA Products

EMC RSA BSAFE Micro Edition Suite MES and others are products of EMC Corporation.EMC RSA BSAFE is a security software product that supports cryptographic algorithms, certificate chain validation, and Transport Layer Security TLS encryption suites, among other things, to help users achieve a wide...

The vulnerability of the OpenSSL library, which allows a hacker to trigger a service failure

The vulnerability of the ssl3getclientkeyexchange function in the OpenSSL library exists due to insufficient validation of input data. Exploiting this vulnerability allows an attacker to cause a service failure by sending a ClientKeyExchange message of zero length during authentication procedures...

OpenSSL DHE Client Key Exchange Denial of Service (CVE-2015-1787)

A denial of service vulnerability exists in OpenSSL. The vulnerability is due to a null pointer dereference that occurs when an OpenSSL application receives and processes a Client Certificate and a crafted Client Key Exchange handshake message.A remote, unauthenticated attacker can exploit this...

OpenSSL 'ssl3_get_client_key_exchange' function denial of service vulnerability

OpenSSL is an open source implementation of SSL used to enable strong encryption of network communications and is now widely used in a variety of web applications. A denial of service vulnerability exists in OpenSSL version 1.0.2. Due to a vulnerability within the implementation of the...

OpenSSL TLS 1.1 and 1.2 AES-NI DoS

The AES-NI implementation of OpenSSL 1.0.1c does not properly compute the length of an encrypted message when used with a TLS version 1.1 or above. This leads to an integer underflow which can cause a DoS. The vulnerable function aesnicbchmacsha1cipher is only included in the 64-bit versions of...

DEBIAN-CVE-2003-0826

lsh daemon lshd does not properly return from certain functions in 1 readline.c, 2 channelcommands.c, or 3 clientkeyexchange.c when long input is provided, which could allow remote attackers to execute arbitrary code via a heap-based buffer overflow attack...
