Apache WSS4J before 1.6.17 and 2.0.x before 2.0.2 improperly leaks information about decryption failures when decrypting an encrypted key or message data, which makes it easier for remote attackers to recover the plaintext form of a symmetric key via a series of crafted messages. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-2487.
Apache WSS4J before 1.6.17 and 2.x before 2.0.2 allows remote attackers to bypass the requireSignedEncryptedDataElements configuration via a vectors related to "wrapping attacks."
The implementations of PKCS#1 v1.5 key transport mechanism for XMLEncryption in JBossWS and Apache WSS4J before 1.6.5 is susceptible to a Bleichenbacher attack.
This package when using TransportBinding, does not properly enforce the SAML SubjectConfirmation method security semantics, which allows remote attackers to conduct spoofing attacks via unspecified vectors.
