curl: OpenSSL provider OSSL_LIB_CTX used after free via the connection shutdown list (CVE-2026-80229 fix incomplete)
Summary: The CVE-2026-80229 fix 7ea37abc6a, 8.22.0 only marks provider connections connclose, but a closed TLS connection is handed to the multi handle's shutdown list lib/conncache.c:242 and outlives its easy handle, while curleasycleanup frees the handle's OSSLLIBCTX osslprovidercleanup,...
Fedora 43 : openssl (2026-93eed17997)
The remote Fedora 43 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-93eed17997 advisory. Rebase to OpenSSL 3.5.9 Tenable has extracted the preceding description block directly from the Fedora security advisory. Note that Nessus has not tested for...
Astra Linux – Vulnerability in Bouncycastle
Bouncy Castle for Java before version 1.73 contains a potential Denial of Service DoS issue within the Bouncy Castle org.bouncycastle.openssl.PEMParser class. This class parses OpenSSL PEM-encoded streams containing X.509 certificates, PKCS8-encoded keys, and PKCS7 objects. Parsing a file that...
Astra Linux – vulnerability in OpenSSL
Issue summary: An invalid or NULL pointer dereference may occur in an application processing a malformed PKCS12 file. Impact summary: An application processing a malformed PKCS12 file may dereference an invalid or NULL pointer during memory read operations, resulting in a Denial of Service. There...
openssl: OpenSSL: Information disclosure and data tampering via specific low-level OCB encryption/decryption calls
A flaw was found in OpenSSL. When applications directly call the low-level CRYPTOocb128encrypt or CRYPTOocb128decrypt functions with non-block-aligned lengths in a single call on hardware-accelerated builds, the trailing 1-15 bytes of a message may be exposed in cleartext. These exposed bytes are...
openssl: openssl: Information Disclosure from Uninitialized Memory via Invalid RSA Public Key
A flaw was found in openssl. Applications that use RSASVE key encapsulation, a method for securely exchanging encryption keys, may inadvertently expose sensitive data. This vulnerability arises when an application processes a malicious, invalid RSA public key provided by an attacker without prope...
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: AES-OCB IV Ignored on EVP_Cipher() Path
A flaw was found in OpenSSL. Applications that use the AES-OCB encryption method with a specific one-shot interface EVPCipher will have their provided Initialization Vector IV silently discarded. This leads to the same internal cryptographic value being used repeatedly, which compromises the...
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...
Important: Red Hat Security Advisory: openssl security update
An update for openssl is now available for Red Hat Enterprise Linux 9.6 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for...
openssl: OpenSSL: Denial of Service due to NULL pointer dereference in CMS EnvelopedData processing
A flaw was found in OpenSSL. A remote attacker could exploit this vulnerability by sending a specially crafted Cryptographic Message Syntax CMS EnvelopedData message. During the processing of a KeyTransportRecipientInfo with RSA-OAEP encryption, the system attempts to access an optional parameter...
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...
io.netty/netty-handler: Netty: TLS hostname verification bypass via OpenSSL client path misconfiguration
A flaw was found in Netty io.netty:netty-handler. When using the SslProvider.OPENSSL client path with a plain X509TrustManager and without Unsafe-based trust-manager wrapping Java 25+, TLS hostname verification is disabled. This misconfiguration allows a man-in-the-middle attacker to present a...
curl: CVE-2026-111878: OpenSSL provider UAF on TLS shutdown
A use-after-free vulnerability was identified in the OpenSSL provider implementation when using the multi interface. The vulnerability occurred when a private library context was freed while an SSL context that borrowed it remained queued for shutdown. This happened because the library context wa...
