Oracle Secure Global Desktop Multiple Vulnerabilities (January 2016 CPU) (Logjam)

The version of Oracle Secure Global Desktop installed on the remote host is version 4.63 / 4.71 / 5.2 and is missing a security patch from the January 2016 Critical Patch Update CPU. It is, therefore, affected by the following vulnerabilities : - A flaw exists in the bundled version of Apache HTT...

What the heck is RFC 5114?

Mandatory Disclaimer: IANAC I am not a cryptographer so I might likely end up writing a bunch of mistakes in this blog post... I already talked about Diffie–Hellman DH from now on in TLS in my previous post: Small subgroup attack in Mozilla NSS. As mentioned FWIW I strongly agree with Google Chro...

Updated bouncycastle packages fix security vulnerability

The Bouncy Castle Java library before 1.51 does not validate a point is withing the elliptic curve, which makes it easier for remote attackers to obtain private keys via a series of crafted elliptic curve Diffie Hellman ECDH key exchanges, aka an "invalid curve attack" CVE-2015-7940...

Small subgroup attack in Mozilla NSS

tl;dr While the TLS servers attacks has been pretty much studied and fixed see e.g. https://www.secure-resumption.com/ and https://weakdh.org/ the situation with the TLS clients is was not ideal and can be improved. Here I report a Small subgroup attack for TLS clients that I performed against...

The vulnerability of the Bouncy Castle cryptographic protection tool and the openSUSE operating system allows a hacker to gain access to the secret key.

The vulnerability of the Bouncy Castle cryptographic protection and the openSUSE operating system is related to errors in the code. Exploiting this vulnerability can allow a remote attacker to gain access to the secret key by making changes to the algorithm based on elliptic curves of...

Debian DLA-361-1 : bouncycastle security update

The Bouncy Castle Java library before 1.51 does not validate that a point is within the elliptic curve, which makes it easier for remote attackers to obtain private keys via a series of crafted elliptic curve Diffie Hellman ECDH key exchanges, aka an 'invalid curve attack.' For Debian 6 'Squeeze'...

OpenSSL 1.0.2 < 1.0.2e Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 1.0.2e. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.2e advisory. - The ASN1TFLGCOMBINE implementation in crypto/asn1/tasndec.c in OpenSSL before 0.9.8zh, 1.0.0 before 1.0.0t, 1.0.1 before 1.0.1q, a...
