openssl: Heap Use-After-Free in OpenSSL PKCS7_verify()
A flaw was found in OpenSSL. When processing a specially crafted PKCS7 or S/MIME Secure/Multipurpose Internet Mail Extensions signed message, a heap use-after-free vulnerability in the PKCS7verify function can be triggered. This occurs if the SignedData digestAlgorithms field is present as an emp...
openssl: Incorrect Tag Processing for Empty Messages in AES-GCM-SIV and AES-SIV modes
A flaw was found in OpenSSL. The implementations of AES-SIV Advanced Encryption Standard - SIV and AES-GCM-SIV Advanced Encryption Standard - Galois/Counter Mode - SIV incorrectly process authentication tags for empty messages. This vulnerability allows a remote attacker to forge empty messages...
openssl: FFC-DH Peer Validation Uses Attacker-Supplied q
A flaw was found in OpenSSL. A malicious peer can exploit this vulnerability by presenting a specially crafted DHX X9.42 peer key. Due to improper validation of the peer key's subgroup membership, an attacker can recover the victim's private key after a small number of key exchange attempts. This...
openssl: NULL Pointer Dereference in CRMF EncryptedValue Decryption
A flaw was found in OpenSSL. An attacker controlling a Certificate Management Protocol CMP server, or acting as a man-in-the-middle, could craft a malicious CMP response. This response, containing a Certificate Request Message Format CRMF CertRepMessage with a specific malformed EncryptedValue...
openssl: Possible NULL Dereference in Password-Based CMS Decryption
A flaw was found in OpenSSL. A remote attacker could exploit a NULL pointer dereference vulnerability in the Cryptographic Message Syntax CMS decryption process by providing a specially crafted password-encrypted CMS message. This occurs because the keyDerivationAlgorithm field, which is optional...
openssl: NULL pointer dereference in QUIC server initial packet handling
A flaw was found in the OpenSSL QUIC Quick UDP Internet Connections server. A remote attacker could send a specially crafted QUIC initial packet with an invalid token. If the server's address validation is explicitly disabled, this could lead to a NULL pointer dereference, causing the server...
openssl: Unbounded Memory Growth in the QUIC PATH_CHALLENGE Handler
A flaw was found in OpenSSL's QUIC PATHCHALLENGE handler. A remote attacker can exploit this vulnerability by flooding a QUIC client or server with specially crafted PATHCHALLENGE frames. This leads to unbounded memory allocation within the local QUIC stack, as the system continuously allocates...
openssl: CMS AuthEnvelopedData Processing May Accept Forged Messages
A flaw was found in OpenSSL's Cryptographic Message Services CMS AuthEnvelopedData processing. An on-path attacker can exploit insufficient input validation on cipher and tag length fields by sending specially crafted CMS messages. This can lead to the forging of messages or bypassing integrity...
openssl: OpenSSL: Heap buffer over-read in ASN.1 decoding can lead to denial of service or information disclosure.
A flaw was found in OpenSSL. An integer truncation vulnerability in the ASN.1 decoder can occur when processing a crafted DER-encoded ASN.1 structure with a primitive element exceeding 2 gigabytes. A remote attacker could exploit this to cause a heap buffer over-read. This may lead to an...
openssl: OpenSSL: Denial of Service due to heap out-of-bounds read in CMS password-based decryption
A flaw was found in OpenSSL. When processing attacker-supplied Cryptographic Message Syntax CMS data using password-based decryption, an attacker can choose a stream-mode Key Encryption Key KEK cipher. This can trigger a heap out-of-bounds read, potentially causing an application crash and leadin...
openssl: OpenSSL: Heap buffer overflow due to signed integer overflow in Unicode output sizing
A flaw was found in OpenSSL. A signed integer overflow vulnerability exists when sizing the destination buffer for Unicode output. This can lead to a heap buffer overflow, which may result in a crash or potentially allow an attacker to execute arbitrary code. Exploitation requires an application ...
