OpenJDK: DSA implementation timing attack (Libraries, 8168728)

A covert timing channel flaw was found in the DSA implementation in the Libraries component of OpenJDK. A remote attacker could possibly use this flaw to extract certain information about the used key via a timing side channel...

Denial Of Service (DoS) Through An Infinite Loop

OpenSSL is vulnerable to denial of service DoS attacks. These attacks are possible because it does not correctly handle ECParameter structures where the curve is over a malformed binary polynomial field. These attacks can be triggered through a session that uses an Elliptic Curve algorithm...

USN-3194-1: OpenJDK 7 vulnerabilities

Karthik Bhargavan and Gaetan Leurent discovered that the DES and Triple DES ciphers were vulnerable to birthday attacks. A remote attacker could possibly use this flaw to obtain clear text data from long encrypted sessions. This update moves those algorithms to the legacy algorithm set and causes...

Protection Mechanism Bypass

OpenSSL is vulnerable to protection mechanism bypass. This is because OpenSSL accepts several variations of certificate signature algorithms and signature encodings. It doesn't then enforce a match between the signature algorithm between the signed and unsigned portions of the certificate. This...

USN-3189-1 linux, linux-raspi2, linux-snapdragon vulnerabilities

Mikulas Patocka discovered that the asynchronous multibuffer cryptographic daemon mcryptd in the Linux kernel did not properly handle being invoked with incompatible algorithms. A local attacker could use this to cause a denial of service system crash. CVE-2016-10147 Qidan He discovered that the...

CVE-2016-1919

The CVE-2016-1919 entry concerns Samsung KNOX 1.0 on Android 4.3 where the eCryptFS key is derived from the user password and a TIMA key. The weakness lies in the eCryptFS-key generation algorithm, enabling potential disclosure of Data-at-Rest from KNOX containers when an attacker has local acces...

openssl: Non-constant time codepath followed for certain operations in DSA implementation

It was discovered that OpenSSL did not always use constant time operations when computing Digital Signature Algorithm DSA signatures. A local attacker could possibly use this flaw to obtain a private DSA key belonging to another user or service running on the same system...

Alvosec: Alvocrypt uses a cryptographically insecure PRNG.

Dear Alvosec bug bounty team, Summary --- A PRNG is an algorithm used to produce random-looking numbers with certain desirable statistical properties. In order for a PRNG to be cryptographically secure it must be resistant to prediction. The generatepass function in Alvocrypt currently uses...
