Description

The design of the W3C XML Signature Syntax and Processing (XMLDsig) recommendation, as implemented in the Sun JDK and JRE 6 Update 14 and earlier uses a parameter that defines an HMAC truncation length (HMACOutputLength) but does not require a minimum for this length. This allows attackers to spoof HMAC-based signatures and bypass authentication by specifying a truncation length with a small number of bits.
