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: 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: 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: compat-openssl: openssl: Information disclosure via DTLS handshake retransmission

A flaw was found in OpenSSL. The Datagram Transport Layer Security DTLS retransmission mechanism fails to properly handle handshake message writes that are suspended before completion. A remote attacker could exploit this vulnerability during handshake message retransmission, causing OpenSSL to...

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: 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 ...

CURL-CVE-2026-80229 OpenSSL provider use-after-free

When performing transfers via libcurl’s multi interface, pooled TLS connections can outlive their originating easy handles. In OpenSSL 3 provider configurations, libcurl attaches an allocated library context to the easy handle's state and passes it to OpenSSL without acquiring an ownership...

OpenSSL pinning bypass

When CURLOPTPINNEDPUBLICKEY is configured alongside options that disable standard peer verification CURLOPTSSLVERIFYPEER = 0 and CURLOPTSSLVERIFYHOST = 0, libcurl fails to enforce public key pinning on connections established without a presented server certificate. Bypassing the pinning check und...
