Descriptions

Unspecified vulnerability in Oracle Java SE 8u77 and Java SE Embedded 8u77 allows remote attackers to affect confidentiality via vectors related to JCE.

Vulnerabilidad no especificada en Oracle Java SE 8u77 y Java SE Embedded 8u77 permite a atacantes remotos afectar a la confidencialidad a través de vectores relacionados con JCE.

It was discovered that the GCM (Galois/Counter Mode) implementation in the JCE component in OpenJDK used a non-constant time comparison when comparing GCM authentication tags. A remote attacker could possibly use this flaw to determine the value of the authentication tag.
