#vulnerability

Google has revealed that its AI-powered fuzzing tool, OSS-Fuzz, has been used to help identify 26 vulnerabilities in various open-source code repositories, including a medium-severity flaw in the OpenSSL cryptographic library. "These particular vulnerabilities represent a milestone for automated vulnerability finding: each was found with AI, using AI-generated and enhanced fuzz targets,"

### Summary Litestar offers multiple methods to return a parsed representation of the request body, as well as extractors that rely on those parsers to map request content to structured data types. Multiple of those parsers do not have size limits when reading the request body into memory, which allows an attacker to cause excessive memory consumption on the server by sending large requests. ### Details The `Request` methods to parse json, msgpack or form-data all read the entire request stream into memory via `await self.body()` without a prior size check or size limit. There may be other places (e.g. extractors) where this can happen. For most formats, a configurable size limit would be sufficient to mitigate this issue. The total request size can also be limited by a proxy (e.g. nginx) in front of the actual application as a workaround. However, for applications that actually want to accept large file uploads via `multipart/form-data`, a simple size limit would not be practical. T...

### Impact A vulnerability has been identified within Rancher Manager whereby applications installed via Rancher Manager Apps Catalog store their Helm values directly into the `Apps` Custom Resource Definition, resulting in any users with `GET` access to it to be able to read any sensitive information that are contained within the Apps’ values. Additionally, the same information leaks into auditing logs when the audit level is set to equal or above 2. Application charts without sensitive data are not affected by this vulnerability. This vulnerability impacts any Helm applications installed on a Rancher Manager cluster, regardless of it being installed via the Marketplace or using the helm cli. Please consult the associated [MITRE ATT&CK - Technique - Exploitation for Privilege Escalation](https://attack.mitre.org/techniques/T1068/) for further information about this category of attack. ### Patches Patched versions include Rancher Manager `2.9.5` and `2.8.10`. The fix ensures that al...

### Impact A vulnerability has been discovered in Steve API (Kubernetes API Translator) in which users can watch resources they are not allowed to access, when they have at least some generic permissions on the type. For example, a user who can get a single secret in a single namespace can get all secrets in every namespace. During a `watch` request for a single ID, the following occurs: - In the case of a watch request for a single resource, Steve API will return a partition with the requested resource in it. In other cases, it will check the user's access when constructing partitions. - When a watch request for a single resource is issued, instead of using a client which impersonates the user making the request, Steve API will use the admin client, which can read all resources. This allows any requester to see the contents of any object such as secret keys, signing certificates, API tokens.

Debian Linux Security Advisory 5815-1 - The Qualys Threat Research Unit discovered several local privilege escalation vulnerabilities in needrestart, a utility to check which daemons need to be restarted after library upgrades. A local attacker can execute arbitrary code as root by tricking needrestart into running the Python interpreter with an attacker-controlled PYTHONPATH environment variable (CVE-2024-48990) or running the Ruby interpreter with an attacker-controlled RUBYLIB environment variable (CVE-2024-48992). Additionally a local attacker can trick needrestart into running a fake Python interpreter (CVE-2024-48991) or cause needrestart to call the Perl module Module::ScanDeps with attacker-controlled files (CVE-2024-11003).

Ubuntu Security Notice 7123-1 - It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate certain SMB messages, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service or possibly expose sensitive information. Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 7121-2 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 7120-2 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 7122-1 - A security issue was discovered in the Linux kernel. An attacker could possibly use this to compromise the system.
