Ubuntu Security Notice 6649-1 - Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. Alfred Peters discovered that Firefox did not properly manage memory when storing and re-accessing data on a networking channel. An attacker could potentially exploit this issue to cause a denial of service.

Ubuntu Security Notice 6648-1 - 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.

From FIPS 140-3 to Common Criteria to DISA STIGs, Red Hat is constantly pursuing the next iteration of compliance for our customers. Red Hat’s mission has long been to bring community innovation to enterprise organizations, packaged in a hardened, production-ready form. This isn’t just about packaging and testing, however; we take extra steps to bring these emerging capabilities in-line with some of the most stringent secure computing standards and requirements in the world. Innovation by itself isn’t enough for public sector agencies or the companies that serve these organizations. Inst

If `pkcs12.serialize_key_and_certificates` is called with both: 1. A certificate whose public key did not match the provided private key 2. An `encryption_algorithm` with `hmac_hash` set (via `PrivateFormat.PKCS12.encryption_builder().hmac_hash(...)` Then a NULL pointer dereference would occur, crashing the Python process. This has been resolved, and now a `ValueError` is properly raised. Patched in https://github.com/pyca/cryptography/pull/10423

OpenOLAT versions 18.1.4 and below and versions 18.1.5 and below suffer from multiple persistent cross site scripting vulnerabilities.

Ubuntu Security Notice 6647-1 - 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 Rose X.25 protocol implementation in 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.

Ubuntu Security Notice 6646-1 - 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 Rose X.25 protocol implementation in 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.

Ubuntu Security Notice 6584-2 - USN-6584-1 fixed several vulnerabilities in Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. This update provides the corresponding updates for CVE-2021-33912 andCVE-2021-33913 in Ubuntu 16.04 LTS. Philipp Jeitner and Haya Shulman discovered that Libspf2 incorrectly handled certain inputs. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to cause a denial of service or execute arbitrary code.

Ubuntu Security Notice 6645-1 - It was discovered that the netfilter connection tracker for netlink in the Linux kernel did not properly perform reference counting in some error conditions. A local attacker could possibly use this to cause a denial of service.

While distilling risk down to a simple numerical score is helpful for many in the security space, it is also an imperfect system that can often leave out important context.
