Legion of the Bouncy Castle TLS Information Disclosure Vulnerability
Legion of the Bouncy Castle is an open source, lightweight cipher package for the Java platform from Legion of the Bouncy Castle Australia.TLS is one of the secure transport layer protocols. An information disclosure vulnerability exists in Legion of the Bouncy Castle TLS versions prior to 1.0.3,...
OpenJDK: untrusted extension directories search path in Launcher (JCE, 8163528)
An untrusted library search path flaw was found in the JCE component of OpenJDK. A local attacker could possibly use this flaw to cause a Java application using JCE to load an attacker-controlled library and hence escalate their privileges...
OpenJDK: DSA implementation timing attack (JCE, 8175106)
A covert timing channel flaw was found in the DSA implementation in the JCE component of OpenJDK. A remote attacker able to make a Java application generate DSA signatures on demand could possibly use this flaw to extract certain information about the used key via a timing side channel...
Design/Logic Flaw
BouncyCastle TLS prior to version 1.0.3, when configured to use the JCE Java Cryptography Extension for cryptographic functions, provides a weak Bleichenbacher oracle when any TLS cipher suite using RSA key exchange is negotiated. An attacker can recover the private key from a vulnerable...

CVE-2017-13098 BouncyCastle JCE TLS Bleichenbacher/ROBOT
BouncyCastle TLS prior to version 1.0.3, when configured to use the JCE Java Cryptography Extension for cryptographic functions, provides a weak Bleichenbacher oracle when any TLS cipher suite using RSA key exchange is negotiated. An attacker can recover the private key from a vulnerable...
TLS implementations may disclose side channel information via discrepancies between valid and invalid PKCS#1 padding
Overview TLS implementations may disclose side channel information via discrepancies between valid and invalid PKCS1 padding, and may therefore be vulnerable to Bleichenbacher-style attacks. This attack is known as a "ROBOT attack". Description CWE-203: Information Exposure Through Discrepancy...
Sweet32 Attack
github.com/minio/minio is vulnerable to the Sweet32 cryptography attack. The library uses a Triple-DES cipher that is vulnerable to birthday attacks, allowing a malicious user to decrypt and obtain cleartext data faster than a standard brute-force attack...

DEBIAN-CVE-2017-3738
There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attack...
CVE-2017-14907
CVE-2017-14907 describes a cryptographic weakness in Android for MSM, Firefox OS for MSM, and QRD Android builds aligned with CAF Linux kernel, caused by a flaw in deriving the disk encryption key that reduces cryptographic strength. Publicly documented as a critical encryption bug affecting Qual...
On "Advanced" Network Security Monitoring
My TaoSecurity News page says I taught 41 classes lasting a day or more, from 2002 to 2014. All of these involved some aspect of network security monitoring NSM. Many times students would ask me when I would create the "advanced" version of the class, usually in the course feedback. I could never...

USN-3497-1: OpenJDK 7 vulnerabilities
It was discovered that the Smart Card IO subsystem in OpenJDK did not properly maintain state. An attacker could use this to specially construct an untrusted Java application or applet to gain access to a smart card, bypassing sandbox restrictions. CVE-2017-10274 Gaston Traberg discovered that th...

Linux Memory Cryptographic Keys Extractor: CryKeX
Some work has been already published regarding the subject of cryptograhic keys security within DRAM. Basically, we need to find something that looks like a key entropic and specific length and then confirm its nature by analyzing the memory structure around it C data types. The idea is to dump...
