CVE-2026-5295

The CVE describes a stack buffer overflow in wolfSSL’s PKCS7 code (wc_PKCS7_DecryptOri() in wolfcrypt/src/pkcs7.c) when handling CMS EnvelopedData with an OtherRecipientInfo (ORI) recipient. A parsed OID longer than 32 bytes is copied into a fixed 32-byte stack buffer (oriOID[MAX_OID_SZ]) without...

CVE-2026-5778 Integer underflow leads to out-of-bounds access in sniffer ChaCha decrypt path.

Integer underflow in wolfSSL packet sniffer = 5.9.0 allows an attacker to cause a program crash in the AEAD decryption path by injecting a TLS record shorter than the explicit IV plus authentication tag into traffic inspected by sslDecodePacket. The underflow wraps a 16-bit length to a large valu...

Rack::Session::Cookie secrets: decrypt failure fallback enables secretless session forgery and Marshal deserialization

Rack::Session::Cookie incorrectly handles decryption failures when configured with secrets:. If cookie decryption fails, the implementation falls back to a default decoder instead of rejecting the cookie. This allows an unauthenticated attacker to supply a crafted session cookie that is accepted ...
