CVE-2026-5295

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...

JLSEC-2026-69

In ssh-agent in OpenSSH before 9.6, certain destination constraints can be incompletely applied. When destination constraints are specified during addition of PKCS11-hosted private keys, these constraints are only applied to the first key, even if a PKCS11 token returns multiple keys...

openssl: OpenSSL: Denial of Service due to type confusion in PKCS#12 file processing

A flaw was found in OpenSSL. This type confusion vulnerability allows a remote attacker to cause a Denial of Service DoS by tricking a user or application into processing a maliciously crafted PKCS12 Personal Information Exchange Syntax Standard file. The vulnerability leads to an invalid or NULL...

openssl: OpenSSL: Denial of Service via type confusion in PKCS#7 signature verification

A flaw was found in OpenSSL. This type confusion vulnerability allows a remote attacker to cause a denial of service DoS by providing specially crafted PKCS7 data to an application that performs signature verification. The vulnerability occurs because the application accesses an ASN1TYPE union...

openssl: OpenSSL: Arbitrary code execution or denial of service through crafted PKCS#12 file

A flaw was found in OpenSSL. When an application processes a maliciously crafted PKCS12 file, an attacker can exploit a stack buffer overflow or a NULL pointer dereference. This can lead to a denial of service DoS by crashing the application, and in some cases, may enable arbitrary code execution...
