The vulnerability of the implementation of the HMAC-SHA-256 mechanism in the GnuTLS cryptographic library allows a perpetrator to carry out an “Lucky 13” attack and a attack that recovers the plaintext.

The vulnerability of the HMAC-SHA-256 mechanism implemented in the GnuTLS cryptographic library is related to errors in the implementation of the cryptographic algorithm. Exploiting this vulnerability allows a malicious actor to perform both a “Lucky 13” attack and an attack that recovers the...

Authentication Bypass

java is vulnerable to authentication bypass. A flaw was found in the way the XML Digital Signature implementation in the JRE handled HMAC-based XML signatures. An attacker could use this flaw to create a crafted signature that could allow them to bypass authentication, or trick a user, applet, or...
