Packet Storm

This is a brief whitepaper that discusses some basic fundamentals for approaching secure design of an application.

Google's American Fuzzy Lop is a brute-force fuzzer coupled with an exceedingly simple but rock-solid instrumentation-guided genetic algorithm. afl++ is a superior fork to Google's afl. It has more speed, more and better mutations, more and better instrumentation, custom module support, etc.

An unsafe use of follow_pfn in get_vaddr_frames in videobuf2 on Linux leads to use-after-free issues or writes to ro-pages.

Red Hat Security Advisory 2022-9110-01 - Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains the RPM packages for Red Hat OpenShift Container Platform 4.9.54.

Ubuntu Security Notice 5788-1 - Hiroki Kurosawa discovered that curl incorrectly handled HSTS support when certain hostnames included IDN characters. A remote attacker could possibly use this issue to cause curl to use unencrypted connections. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 22.10. It was discovered that curl incorrectly handled denials when using HTTP proxies. A remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code.

Ubuntu Security Notice 5789-1 - It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code. Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA mappings in some situations, leading to potential data structure reuse. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5782-2 - USN-5782-1 fixed vulnerabilities in Firefox. The update introduced several minor regressions. This update fixes the problem.

Ubuntu Security Notice 5787-1 - It was discovered that Libksba incorrectly handled parsing CRL signatures. A remote attacker could use this issue to cause Libksba to crash, resulting in a denial of service, or possibly execute arbitrary code.

SimpleRmiDiscoverer is a JMX RMI scanning tool for unsecured (without enabled authentication) instances of JAVA JMX. It does not use standard Java RMI/JMX classes like other available tools but rather communicates directly over TCP. The tool is written in Java and is very useful in red teaming operations because JVM is still ubiquitous in corporate environments. It can be executed by unprivileged (non-admin) users.
