PT-2026-67512

Name of the Vulnerable Software and Affected Versions FirmaCheck for Windows versions prior to 1.3.16 Description A DLL hijacking issue exists where local attackers can execute arbitrary code. This occurs by placing a crafted openssl.cnf file in the unvalidated C:Program Files x86Common FilesSSL...

PT-2026-76173

Issue summary: Remote peer may exhaust heap memory of the QUIC server or client by flooding it with packets containing PATH CHALLENGE frames. Impact summary: A malicious remote peer can cause an unbounded memory allocation which can lead to an abnormal termination of the application acting as a...

PT-2026-76182

Issue summary: A specially crafted PKCS7 or S/MIME signed message could trigger a use-after-free during PKCS7 signature verification. Impact summary: A use-after-free may result in process crashes, heap corruption, or potentially remote code execution. When processing a PKCS7 or S/MIME signed...

PT-2026-76192

Issue summary: A signed integer overflow when sizing the destination buffer for Unicode output in ASN1 mbstring ncopy can lead to a heap buffer overflow. Impact summary: A heap buffer overflow may lead to a crash or possibly attacker controlled code execution or other undefined behaviour. In ASN1...

PT-2026-76170

Issue summary: Parsing a crafted DER-encoded ASN.1 structure with a primitive element whose content exceeds 2 gigabytes in length may cause a heap buffer over-read on 64-bit Unix and Unix-like platforms. Impact summary: The heap buffer over-read may crash the application Denial of Service or to...

PT-2026-76174

Issue summary: Receiving a QUIC initial packet with an invalid token may trigger a NULL pointer dereference in the OpenSSL QUIC server with address validation disabled. Impact summary: NULL pointer dereference typically causes abnormal termination of the affected QUIC server process and a Denial ...

PT-2026-76180

Issue summary: When an application drives an AES-OCB context through the public EVP Cipher one-shot interface, the application-supplied initialisation vector IV is silently discarded. Impact summary: Every message encrypted under the same key uses the same effective nonce regardless of the IV...

PT-2026-76176

Issue summary: An attacker-controlled CMP Certificate Management Protocol server could trigger a NULL pointer dereference in a CMP client application. Impact summary: A NULL pointer dereference causes a crash of the application and a Denial of Service. An attacker controlling a CMP server or acti...

PT-2026-76175

Issue summary: A specially crafted password-encrypted CMS message can trigger a NULL pointer dereference during CMS decryption. Impact summary: This NULL pointer dereference leads to an application crash and a Denial of Service. The CMS PasswordRecipientInfo.keyDerivationAlgorithm field is define...

PT-2026-76172

Issue Summary: Cryptographic Message Services CMS processing fails to perform sufficient input validation on the cipher and tag length fields of AuthEnvelopedData containers, leading to various potential compromises. Impact Summary: Attackers making use of these vulnerabilities may achieve...

PT-2026-76177

Issue summary: The CMS decrypt and PKCS7 decrypt functions are vulnerable to Bleichenbacher-style attack when an attacker is able to provide the CMS or S/MIME messages and observe the error code and/or decryption output. Impact summary: The Bleichenbacher-style attack allows an attacker to use th...

PT-2026-76178

Issue Summary: An error in the callback used to verify the certificate provided in a Root CA key update Certificate Management Protocol CMP message response rendered the certificate validation ineffectual, which could lead to escalation of credentials from the Registration Authority RA level to t...

PT-2026-76179

Issue summary: When EVP PKEY derive set peer is called with a DHX X9.42 peer key, the peer key is not properly checked for the subgroup membership. Impact summary: A malicious peer which presents an X9.42 key carrying the victim's p and g parameters, a forged q = r a small prime factor of the...

PT-2026-76181

Issue summary: The implementations of AES-SIV RFC 5297 and AES-GCM-SIV RFC 8452 mishandle the authentication of AAD Additional Authenticated Data with an empty ciphertext allowing a forgery of such messages. Impact summary: An attacker can forge empty messages with arbitrary AAD to the victim's...

PT-2026-76193

Issue summary: When CMS password-based decryption RFC 3211 / PWRI key unwrap processes attacker-supplied CMS data, an attacker-chosen stream-mode KEK cipher can trigger a heap out-of-bounds read in kek unwrap key. Impact summary: A heap buffer over-read may trigger a crash which leads to Denial o...
