Vulnerability from csaf_redhat - Published: 2026-09-24 11:15 - Updated: 2026-10-07 17:15Summary
Red Hat Security Advisory: openssl security update
Severity
Important
Notes
Topic: An update for openssl is now available for Red Hat Enterprise Linux 10.0 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 each vulnerability from the CVE link(s) in the References section.
Details: OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.
Security Fix(es):
* openssl: OpenSSL: Information disclosure and data tampering via specific low-level OCB encryption/decryption calls (CVE-2025-69418)
* openssl: openssl: Information Disclosure from Uninitialized Memory via Invalid RSA Public Key (CVE-2026-31790)
* openssl: OpenSSL: Denial of Service due to NULL pointer dereference in CMS EnvelopedData processing (CVE-2026-28390)
* openssl: CMS AuthEnvelopedData Processing May Accept Forged Messages (CVE-2026-34182)
* openssl: Unbounded Memory Growth in the QUIC PATH_CHALLENGE Handler (CVE-2026-34183)
* openssl: AES-OCB IV Ignored on EVP_Cipher() Path (CVE-2026-45445)
* openssl: Heap Use-After-Free in OpenSSL PKCS7_verify() (CVE-2026-45447)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A flaw was found in OpenSSL. When applications directly call the low-level CRYPTO_ocb128_encrypt() or CRYPTO_ocb128_decrypt() 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 not covered by the authentication tag, allowing an attacker to read or tamper with them without detection.

Threats
Impact
Low
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 field without first verifying its presence. This leads to a NULL pointer dereference, which can cause applications processing the attacker-controlled CMS data to crash, resulting in a Denial of Service (DoS).

Threats
Impact
Moderate
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 proper validation. Consequently, the application might send the contents of an uninitialized memory buffer, which could contain confidential information, to the attacker.

CVE-2025-69418
Threats
Impact
Moderate
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 validation. Consequently, an attacker may achieve key-equivalent functionality for a given CMS recipient.

8 products, the same list as for
CVE-2025-69418
Threats
Impact
Moderate
A flaw was found in OpenSSL's QUIC PATH_CHALLENGE handler. A remote attacker can exploit this vulnerability by flooding a QUIC client or server with specially crafted PATH_CHALLENGE frames. This leads to unbounded memory allocation within the local QUIC stack, as the system continuously allocates PATH_RESPONSE frames without them being acknowledged. The primary consequence is a Denial of Service (DoS), causing the affected application to terminate abnormally due to memory exhaustion.

8 products, the same list as for
CVE-2025-69418
Threats
Impact
Moderate
A flaw was found in OpenSSL. Applications that use the AES-OCB encryption method with a specific one-shot interface (EVP_Cipher()) will have their provided Initialization Vector (IV) silently discarded. This leads to the same internal cryptographic value being used repeatedly, which compromises the confidentiality of encrypted data. Additionally, this issue allows for the universal forgery of authentication tags, undermining the integrity of communications.

Known not affected
8 products, the same list as for
CVE-2025-69418
Threats
Impact
Moderate
A flaw was found in OpenSSL. When processing a specially crafted PKCS#7 or S/MIME (Secure/Multipurpose Internet Mail Extensions) signed message, a heap use-after-free vulnerability in the PKCS7_verify() function can be triggered. This occurs if the SignedData digestAlgorithms field is present as an empty ASN.1 SET, leading to incorrect memory deallocation. A remote attacker could exploit this to cause application crashes, memory corruption, or potentially achieve remote code execution.

During the processing of a KeyTransportRecipientInfo with RSA-OAEP encryption, the system attempts to access an optional parameter field without first verifying its presence. This leads to a NULL pointer dereference, which can cause applications processing the attacker-controlled CMS data to crash, resulting in a Denial of Service (DoS).",

The vulnerable path requires:\nCMS/S/MIME processing,\nspecifically CMS_decrypt(),\nwith RSA-OAEP KeyTransportRecipientInfo.\nMany OpenSSL consumers never use CMS APIs, never process S/MIME,\nor do not decrypt attacker-controlled CMS objects.\nSo exposure is far narrower than a generic TLS parsing vulnerability.",

Consequently, the application might send the contents of an uninitialized memory buffer, which could contain confidential information, to the attacker.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
