Ubuntu Security Notice 6651-2 - It was discovered that a race condition existed in the ATM subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition existed in the AppleTalk networking subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Red Hat Security Advisory 2024-1027-03 - An update is now available for MTA-6.2-RHEL-8 and MTA-6.2-RHEL-9. Issues addressed include XML injection and denial of service vulnerabilities.

Ubuntu Security Notice 6648-2 - It was discovered that a race condition existed in the AppleTalk networking subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Zhenghan Wang discovered that the generic ID allocator implementation in the Linux kernel did not properly check for null bitmap when releasing IDs. A local attacker could use this to cause a denial of service.

Red Hat Security Advisory 2024-0269-03 - An update for run-once-duration-override-container, run-once-duration-override-operator-bundle-container, and run-once-duration-override-operator-container is now available for RODOO-1.1-RHEL-9. Issues addressed include a denial of service vulnerability.

Transparent TLS (TTLS) is a MarbleRun feature that wraps plain TCP connections between Marbles in TLS. In the manifest, a user defines the connections that should be considered. ### Impact If a Marble is configured for TTLS, but doesn't have an environment variable defined in its parameters, TTLS is not applied. The traffic will not be encrypted. MarbleRun deployments that don't use TTLS (which is only available with EGo Marbles) are not affected. ### Patches The issue has been patched in [`v1.4.1`](https://github.com/edgelesssys/marblerun/releases/tag/v1.4.1). ### Workarounds Make sure that all Marbles that use TTLS have an environment variable defined in their parameters. ### References For a description of TTLS, see <https://docs.edgeless.systems/marblerun/features/transparent-TLS> See the updated section on TTLS configuration in the manifest: <https://docs.edgeless.systems/marblerun/workflows/define-manifest#tls>

Ubuntu Security Notice 6663-1 - As a security improvement, this update prevents OpenSSL from returning an error when detecting wrong padding in PKCS#1 v1.5 RSA, to prevent its use in possible Bleichenbacher timing attacks.

Ubuntu Security Notice 6662-1 - Yi Yang discovered that the Hotspot component of OpenJDK 21 incorrectly handled array accesses in the C1 compiler. An attacker could possibly use this issue to cause a denial of service, execute arbitrary code or bypass Java sandbox restrictions. It was discovered that the Hotspot component of OpenJDK 21 did not properly verify bytecode in certain situations. An attacker could possibly use this issue to bypass Java sandbox restrictions.

Ubuntu Security Notice 6661-1 - Yi Yang discovered that the Hotspot component of OpenJDK 17 incorrectly handled array accesses in the C1 compiler. An attacker could possibly use this issue to cause a denial of service, execute arbitrary code or bypass Java sandbox restrictions. It was discovered that the Hotspot component of OpenJDK 17 did not properly verify bytecode in certain situations. An attacker could possibly use this issue to bypass Java sandbox restrictions.

Ubuntu Security Notice 6660-1 - Yi Yang discovered that the Hotspot component of OpenJDK 11 incorrectly handled array accesses in the C1 compiler. An attacker could possibly use this issue to cause a denial of service, execute arbitrary code or bypass Java sandbox restrictions. It was discovered that the Hotspot component of OpenJDK 11 did not properly verify bytecode in certain situations. An attacker could possibly use this issue to bypass Java sandbox restrictions.
