Forge has signature forgery in RSA-PKCS due to ASN.1 extra field

Summary RSASSA PKCS1 v1.5 signature verification accepts forged signatures for low public exponent keys e=3. Attackers can forge signatures by stuffing “garbage” bytes within the ASN structure in order to construct a signature that passes verification, enabling Bleichenbacher style forgery. This...

libcrux: Panic in Signature Hint Decoding During Verification

During ML-DSA verification the serialized hint values are decoded as specified in algorithm 22 HintBitUnpack of FIPS 204, subsection 7.1. The algorithm requires that the cumulative hint counters per row of the hint vector are strictly increasing and below a maximum value which depends on the choi...

CVE-2026-33487

The CVE-2026-33487 in goxmldsig affects the validateSignature logic in validate.go prior to v1.6.0. In Go versions before 1.22 (or when a older module version is used), a loop variable capture bug stores the address of the loop variable, causing the ref pointer to end up pointing to the last matc...
