Updated openssl packages fix security vulnerabilities

The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a Affected 1.1.1. Fixed in OpenSSL 1.1.0j Affected 1.1.0-1.1.0i. Fixed in OpenSSL 1.0.2q...

x86: DoS from attempting to use INVPCID with a non-canonical addresses

ISSUE DESCRIPTION The INVPCID instruction raises GP0 if an attempt is made to invalidate a non-canonical address. Older flushing mechanisms such as INVLPG tolerate this without error, and perform no action. There is one guest accessible path in Xen where a non-canonical address was passed into th...

Simultaneous Multi-threading SMT in processors can enable local users to exploit software vulnerable to timing attacks via a side-channel timing attack on 'port contention'...

CVE-2018-5407

CVE-2018-5407 is a PortSmash timing-side channel vulnerability in SMT/Hyper-Threading affecting OpenSSL. Local attackers could exploit a timing leakage during cryptographic operations to gain information. Documented in multiple advisories (e.g., ALAS/ALAS2 for OpenSSL) with remediation stating to...

The x86 Processor Fuzzer: sandsifter

Your computer is not yours. You may have shelled out thousands of dollars for it. It may be sitting right there on your desk. You may have carved your name deep into its side with a blowtorch and chisel. But it’s still not yours. Some vendors are building secret processor registers into your...

Which Threats had the Most Impact During the First Half of 2018?

One of the best ways for organizations to shore up their data security efforts and work toward more proactive protection is by examining trends within the threat environment. Taking a look at the strategies for attack, infiltration and infection currently being utilized by hackers can point towar...
