CVE-2026-5500

CVE-2026-5500 affects wolfSSL (library) in wc_PKCS7_DecodeAuthEnvelopedData; the AES-GCM authentication tag length is not properly validated (no lower bound), allowing a MITM to truncate the MAC from 16 bytes to 1 byte and reduce tag verification strength from 2^-128 to 2^-8. This is described in...

EUVD-2026-21228

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...

Stack-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Stack-based Buffer Overflow in the wcPKCS7DecryptOri function when processing a CMS EnvelopedData message containing an OtherRecipientInfo recipient. An attacker can execute arbitrary code or cause a crash by sending a crafted message...
