Ubuntu Security Notice 7018-1 - Robert Merget, Marcus Brinkmann, Nimrod Aviram, and Juraj Somorovsky discovered that certain Diffie-Hellman ciphersuites in the TLS specification and implemented by OpenSSL contained a flaw. A remote attacker could possibly use this issue to eavesdrop on encrypted communications. This was fixed in this update by removing the insecure ciphersuites from OpenSSL. Paul Kehrer discovered that OpenSSL incorrectly handled certain input lengths in EVP functions. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service.

Red Hat Security Advisory 2024-2447-03 - An update for openssl and openssl-fips-provider is now available for Red Hat Enterprise Linux 9. Issues addressed include a denial of service vulnerability.

Ubuntu Security Notice 6709-1 - It was discovered that checking excessively long DH keys or parameters may be very slow. A remote attacker could possibly use this issue to cause OpenSSL to consume resources, resulting in a denial of service. After the fix for CVE-2023-3446 Bernd Edlinger discovered that a large q parameter value can also trigger an overly long computation during some of these checks. A remote attacker could possibly use this issue to cause OpenSSL to consume resources, resulting in a denial of service.

Ubuntu Security Notice 6632-1 - David Benjamin discovered that OpenSSL incorrectly handled excessively long X9.42 DH keys. A remote attacker could possibly use this issue to cause OpenSSL to consume resources, leading to a denial of service. Bahaa Naamneh discovered that OpenSSL incorrectly handled certain malformed PKCS12 files. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service.

Red Hat Security Advisory 2024-0208-03 - An update for openssl is now available for Red Hat Enterprise Linux 8.6 Extended Update Support.

Red Hat Security Advisory 2023-7877-03 - An update for openssl is now available for Red Hat Enterprise Linux 8.

An issue exists in SoftIron HyperCloud where compute nodes may come online immediately without following the correct initialization process.  In this instance, workloads may be scheduled on these nodes and deploy to a failed or erroneous state, which impacts the availability of these workloads that may be deployed during this time window. This issue impacts HyperCloud versions from 2.0.0 to before 2.0.3.

Issue summary: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or parameters may be very slow. Impact summary: Applications that use the functions DH_generate_key() to generate an X9.42 DH key may experience long delays. Likewise, applications that use DH_check_pub_key(), DH_check_pub_key_ex() or EVP_PKEY_public_check() to check an X9.42 DH key or X9.42 DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source this may lead to a Denial of Service. While DH_check() performs all the necessary checks (as of CVE-2023-3817), DH_check_pub_key() doesn't make any of these checks, and is therefore vulnerable for excessively large P and Q parameters. Likewise, while DH_generate_key() performs a check for an excessively large P, it doesn't check for an excessively large Q. An application that calls DH_generate_key() or DH_check_pub_key() and supplies a key or parameters obtaine...
