Security Advisory - OpenSSL Montgomery multiplication may produce incorrect results Vulnerability

The Broadwell-specific Montgomery multiplication procedure has a denial of service DoS vulnerability when handling input longer than 256 bits.Only EC algorithms that use Brainpool P-512 curves are affected. An attacker could exploit this vulnerability to cause DoS during ECDH key...

F5 Networks BIG-IP : OpenSSL vulnerability (K43570545)

There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure in OpenSSL 1.0.2 and 1.1.0 before 1.1.0c that handles input lengths divisible by, but longer than 256 bits. Analysis suggests that attacks against RSA, DSA and DH private keys are impossible. This is...

Updated openssl packages fix security vulnerability

There is a carry propagation bug in the Broadwell-specific Montgomery multiplication procedure that handles input lengths divisible by, but longer than 256 bits. mong EC algorithms only Brainpool P-512 curves are affected and one presumably can attack ECDH key negotiation CVE-2016-7055. If an...

OpenSSL 1.0.2 < 1.0.2k Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 1.0.2k. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.2k advisory. - There is a carry propagating bug in the x8664 Montgomery squaring procedure in OpenSSL 1.0.2 before 1.0.2k and 1.1.0 before 1.1.0d...

OpenSSL Patches High-Severity Denial-of-Service Bug

OpenSSL on Thursday patched three vulnerabilities in its latest update, and reminded users running version 1.0.1 of the cryptographic library that that security support will end Dec. 31. Of the three bugs, only one was rated high severity and could lead to OpenSSL crashes. Only OpenSSL 1.1.0 is...
