Red Hat Security Advisory: Red Hat JBoss Enterprise Application Platform 8.1.6 security update

Important

A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcprov. The `GOSTCTR` implementation is unable to securely process more than 255 blocks of data due to keystream reuse. This issue allows an attacker to break the fundamental confidentiality of any data protected by the `G3413CTRBlockCipher`, potentially leading to the recovery and access of encrypted data.

CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

A flaw was found in Wildfly Elytron integration. The component does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks via CLI.

CWE-307 - Improper Restriction of Excessive Authentication Attempts

A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcprov. The `LDAPStoreHelper` implementation fails to properly neutralize special elements in user-supplied input before incorporating them into LDAP queries. This allows a remote attacker to execute an LDAP injection attack by supplying crafted input, potentially leading to disclosure of sensitive information or the manipulation of directory search queries.

CWE-90 - Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection')

A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpg. A specially crafted PGP AEAD (Authenticated Encryption with Associated Data) message with an unbounded chunk size can lead to an excessive consumption of memory. This issue allows an unauthenticated remote attacker to cause memory exhaustion in a JVM, resulting in a denial of service.

CWE-770 - Allocation of Resources Without Limits or Throttling

A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpkix. The PKIX draft `CompositeVerifier` implementation improperly accepts an empty signature sequence as a valid cryptographic signature. This issue allows a remote attacker to bypass signature verification mechanisms, potentially compromising the authenticity and integrity of data.

CWE-347 - Improper Verification of Cryptographic Signature

A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA core. A covert timing channel vulnerability, caused by non-constant time comparisons, risks the leakage of private keys in the FrodoKEM implementation. An unauthenticated, remote attacker can potentially exploit this timing discrepancy to gain unauthorized access to sensitive cryptographic information.

CWE-385 - Covert Timing Channel

A flaw was found in minimatch. A remote attacker could exploit this Regular Expression Denial of Service (ReDoS) vulnerability by providing a specially crafted glob pattern. This pattern, containing numerous consecutive wildcard characters, causes excessive processing and exponential backtracking in the regular expression engine. Successful exploitation leads to a Denial of Service (DoS), making the application unresponsive.

CWE-1333 - Inefficient Regular Expression Complexity

A flaw was found in Apache Artemis and Apache ActiveMQ Artemis. An unauthenticated remote attacker can exploit a missing authentication for critical function vulnerability by using the Core protocol. This allows the attacker to force a target broker to establish an outbound Core federation connection to an attacker-controlled rogue broker. The primary consequence is the potential for message injection into any queue and/or message exfiltration from any queue via the rogue broker.

CWE-306 - Missing Authentication for Critical Function
