The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2018-3050 advisory. - Improved counter-measures in TLS CBC record padding for lucky13 attack CVE-2018-10844, 1589704, CVE-2018-10845, 1589707 - Added counter-measures for...

Medium: openssl

Issue Overview: During key agreement in a TLS handshake using a DHE based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client ha...

PortSmash Side Channel Attack Siphons Data From Intel, Other CPUs

Yet another side-channel attack, this time dubbed PortSmash, has been discovered in CPUs. The attack allows attackers to manipulate a glitch in the simultaneous multithreading SMT architecture used in CPUs — and siphon processed data from chips. Several attacks have popped up over the past year...
