ALPINE-CVE-2018-0488

ARM mbed TLS before 1.3.22, before 2.1.10, and before 2.7.0, when the truncated HMAC extension and CBC are used, allows remote attackers to execute arbitrary code or cause a denial of service heap corruption via a crafted application packet within a TLS or DTLS session...

What You Should Know About Side-Channel Attacks, Like Meltdown

“The light is on in their window. They must be home.” This is a classic example of a side information channel. They didn’t TELL you they were home. But the side effect of them being home in the evening is the light in the window — which is how you’re pretty sure they are home even though this...

CVE-2018-1388

GSKit V7 may disclose side channel information via discrepancies between valid and invalid PKCS1 padding. IBM X-Force ID: 138212...

Weak ElGamal Cryptography

Pycryptodome uses weak ElGamal cryptography. Due to an incorrect implementation of ElGamal, the Decisional Diffie-Hellman DDH assumption doesnt hold because of the way the key parameters are generated. This allows attackers who have access to the cipher-text to decrypt the messages and potentiall...

Weak ElGamal Parameters

PyCrypto uses weak ElGamal cryptography. Due to an incorrect implementation of ElGamal, the Decisional Diffie-Hellman DDH assumption doesn't hold because of the way the key parameters are generated. This allows attackers who have access to the cipher-text to decrypt the messages and potentially...

PYSEC-2018-97

lib/Crypto/PublicKey/ElGamal.py in PyCrypto through 2.6.1 generates weak ElGamal key parameters, which allows attackers to obtain sensitive information by reading ciphertext data i.e., it does not have semantic security in face of a ciphertext-only attack. The Decisional Diffie-Hellman DDH...

The vulnerability of Sonatype Nexus Repository Manager, related to the use of cryptographic algorithms containing defects, allows a perpetrator to gain access to authentication data.

The vulnerability of Sonatype Nexus Repository Manager is related to the use of cryptographic algorithms that contain vulnerabilities. Exploiting this vulnerability could allow a malicious actor, operating remotely, to gain access to user authentication data and other sensitive information...

SSL/TLS Services Support RC4 (PCI DSS)

At least one of the SSL or TLS services on the remote host supports the use of RC4 for encryption. RC4 does not meet the PCI definition of strong cryptography as defined by NIST Special Publication 800-57 Part 1. The RC4 cipher is flawed in its generation of a pseudo-random stream of bytes so tha...

Weak DH Key Exchange Supported (PCI DSS)

At least one of the services on the remote host supports a Diffie-Hellman key exchange using a public modulus smaller than 2048 bits. Diffie-Hellman key exchanges with keys smaller than 2048 bits do not meet the PCI definition of strong cryptography as specified by NIST Special Publication 800-57...

Wallarm Podcast: Security Challenges of 2017 and Predictions for 2018

Right before Christmas, we have invited several security professionals to a roundtable event where we discussed how AI is affecting cybersecurity landscape. While we had them on as panelists, we have asked Richard Seiersen, Bill Chen and Sean Todd to share their views on the biggest security...

OpenJDK: insufficient strength of key agreement (JCE, 8185292)

It was discovered that the key agreement implementations in the JCE component of OpenJDK did not guarantee sufficient strength of used keys to adequately protect generated shared secret. This could make it easier to break data encryption by attacking key agreement rather than the encryption using...

Il (triste??) stato della crittografia (applicata) in Italia

Ho appena finito di scrivere a proposito dei miei 3 giorni trascorsi al Real World Crypto 2018 il blog post per chi legge inglese e' qui e mi sono accorto che non c'e' traccia di nessuna Universita' ma anche azienda italiana. Tutto cio' non puo' che rendermi un po' triste. L'Italia aveva una...

Real World Crypto 2018 (RWC 2018) brain dump

The 2018 edition of Real World Crypto RWC was in Zurich you can find the conference full program here.. I live in Switzerland so I was extremely happy about it. RWC is basically the best conference I ever attended and it will probably be so for a while. I almost risked to skip it due to flu but I...
