Important: python-pyasn1

Issue Overview: pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets without an upper bound on the tag ID size, allowing a crafted input to force construction of an arbitrarily larg...

CVE-2026-55731

JLSEC-2026-714

Two potential heap out-of-bounds write locations existed in DecodeObjectId in wolfcrypt/src/asn.c. First, a bounds check only validates one available slot before writing two OID arc values out0 and out1, enabling a 2-byte out-of-bounds write when outSz equals 1. Second, multiple callers pass...

Missing hash/digest size and OID checks allow digests smaller than allowed when verifying ECDSA certificates, or smaller than is appropriate for the relevant key type, to be accepted by signature verification functions. This could lead to reduced security of ECDSA certificate-based authentication...

JLSEC-2026-719

A stack buffer overflow exists in wolfSSL's PKCS7 implementation in the wcPKCS7DecryptOri function in wolfcrypt/src/pkcs7.c. When processing a CMS EnvelopedData message containing an OtherRecipientInfo ORI recipient, the function copies an ASN.1-parsed OID into a fixed 32-byte stack buffer...
