Good cyber security practices depend on trustworthy information sources about security vulnerabilities. This article offers guidance around who to trust for this information.In 1999, MITRE Corporation, a US Government-funded research and development company, realized the world needed a uniform standard for reporting and tracking software security bugs. MITRE worked with the IT industry to invent a concept called CVE, for Common Vulnerabilities and Exposures. The CVE concept caught on, and today, the industry acknowledges CVE as the universal standard for security vulnerability reporting.Softw

### Impact If GeoServer is deployed in the Windows operating system using an Apache Tomcat web application server, it is possible to bypass existing input validation in the GeoWebCache ByteStreamController class and read arbitrary classpath resources with specific file name extensions. If GeoServer is also deployed as a web archive using the data directory embedded in the geoserver.war file (rather than an external data directory), it will likely be possible to read specific resources to gain administrator privileges. However, it is very unlikely that production environments will be using the embedded data directory since, depending on how GeoServer is deployed, it will be erased and re-installed (which would also reset to the default password) either every time the server restarts or every time a new GeoServer WAR is installed and is therefore difficult to maintain. An external data directory will always be used if GeoServer is running in standalone mode (via an installer or a bina...

GeoServer's Server Status page and REST API (at `/geoserver/rest/about/status`) lists *all* environment variables and Java properties to *any* GeoServer user with administrative rights as part of those modules' status message. These variables/properties can also contain sensitive information, such as database passwords or API keys/tokens, for example: * Data stores defined with [parameterized catalog settings][catalog] (`-DALLOW_ENV_PARAMETRIZATION=true`) which need a password or access key. * GeoServer's official Docker image [uses environment variables to configure PostgreSQL JNDI resources, including credentials][docker-jndi] (`POSTGRES_HOST`, `POSTGRES_USERNAME`, `POSTGRES_PASSWORD`) Additionally, many community-developed GeoServer container images `export` other credentials from their start-up scripts as environment variables to the GeoServer (`java`) process, such as: * GeoServer `admin` and master (`root`) passwords * Tomcat management application password * HTTPS/TLS cer...

Debian Linux Security Advisory 5724-1 - The Qualys Threat Research Unit (TRU) discovered that OpenSSH, an implementation of the SSH protocol suite, is prone to a signal handler race condition. If a client does not authenticate within LoginGraceTime seconds (120 by default), then sshd's SIGALRM handler is called asynchronously and calls various functions that are not async-signal-safe. A remote unauthenticated attacker can take advantage of this flaw to execute arbitrary code with root privileges. This flaw affects sshd in its default configuration.

Gentoo Linux Security Advisory 202407-8 - Multiple vulnerabilities have been discovered in GNU Emacs and Org Mode, the worst of which could lead to arbitrary code execution. Versions greater than or equal to 26.3-r16:26 are affected.

Gentoo Linux Security Advisory 202407-7 - A vulnerability has been discovered in cpio, which can lead to arbitrary code execution. Versions greater than or equal to 2.13-r1 are affected.
