Ubuntu Security Notice 5682-1 - It was discovered that the BPF verifier in the Linux kernel did not properly handle internal data structures. A local attacker could use this to expose sensitive information. It was discovered that an out-of-bounds write vulnerability existed in the Video for Linux 2 implementation in the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

GoCD is a continuous delivery server. GoCD helps you automate and streamline the build-test-release cycle for continuous delivery of your product. GoCD versions from 19.2.0 to 19.10.0 (inclusive) are subject to a timing attack in validation of access tokens due to use of regular string comparison for validation of the token rather than a constant time algorithm. This could allow a brute force attack on GoCD server API calls to observe timing differences in validations in order to guess an access token generated by a user for API access. This issue is fixed in GoCD version 19.11.0. As a workaround, users can apply rate limiting or insert random delays to API calls made to GoCD Server via a reverse proxy or other fronting web server. Another workaround, users may disallow use of access tokens by users by having an administrator revoke all access tokens through the "Access Token Management" admin function.

With each passing year, the cybersecurity threat landscape continues to worsen. That reality makes cybersecurity analysts some of the most sought-after technology professionals in the world. And there are nowhere near enough of them to meet the demand. At last count, there were over 3.5 million unfilled cybersecurity jobs worldwide — and that number is still growing. The situation means that

Web infrastructure and security company Cloudflare disclosed this week that it halted a 2.5 Tbps distributed denial-of-service (DDoS) attack launched by a Mirai botnet. Characterizing it as a "multi-vector attack consisting of UDP and TCP floods," researcher Omer Yoachimik said the DDoS attack targeted the Minecraft server Wynncraft in Q3 2022. "The entire 2.5 Tbps attack lasted about 2 minutes,

Grafana is an open source observability and data visualization platform. Versions of Grafana for endpoints prior to 9.1.8 and 8.5.14 could leak authentication tokens to some destination plugins under some conditions. The vulnerability impacts data source and plugin proxy endpoints with authentication tokens. The destination plugin could receive a user's Grafana authentication token. Versions 9.1.8 and 8.5.14 contain a patch for this issue. As a workaround, do not use API keys, JWT authentication, or any HTTP Header based authentication.

Grafana is an open source observability and data visualization platform. Starting with version 5.0.0-beta1 and prior to versions 8.5.14 and 9.1.8, Grafana could leak the authentication cookie of users to plugins. The vulnerability impacts data source and plugin proxy endpoints under certain conditions. The destination plugin could receive a user's Grafana authentication cookie. Versions 9.1.8 and 8.5.14 contain a patch for this issue. There are no known workarounds.

Grafana is an open source observability and data visualization platform. Versions prior to 9.1.8 and 8.5.14 are vulnerable to a bypass in the plugin signature verification. An attacker can convince a server admin to download and successfully run a malicious plugin even though unsigned plugins are not allowed. Versions 9.1.8 and 8.5.14 contain a patch for this issue. As a workaround, do not install plugins downloaded from untrusted sources.

A timing attack helps cyberattackers lob malicious code-bombs at corporate targets by cloning private package names.

### Impact A potential remote command execution issue exists within `redshift-jdbc42` versions 2.1.0.7 and below. When plugins are used with the driver, it instantiates plugin instances based on Java class names provided via the `sslhostnameverifier`, `socketFactory`, `sslfactory`, and `sslpasswordcallback` connection properties. In affected versions, the driver does not verify if a plugin class implements the expected interface before instantiatiaton. This can lead to loading of arbitrary Java classes, which a knowledgeable attacker with control over the JDBC URL can use to achieve remote code execution. ### Patches This issue is patched within `redshift-jdbc-42` 2.1.0.8 and above. ### Workarounds We advise customers using plugins to upgrade to `redshift-jdbc42` version 2.1.0.8 or above. There are no known workarounds for this issue. ### For more information If you have any questions or comments about this advisory, please contact AWS Security at [[email protected]](mailt...
