Red Hat Security Advisory 2022-6271-01 - This advisory contains the container images for Red Hat Advanced Cluster Management for Kubernetes, which fix several bugs. Issues addressed include a denial of service vulnerability.

Helm is a tool for managing Charts. Charts are packages of pre-configured Kubernetes resources. Fuzz testing, provided by the CNCF, identified input to functions in the _strvals_ package that can cause an out of memory panic. The _strvals_ package contains a parser that turns strings in to Go structures. The _strvals_ package converts these strings into structures Go can work with. Some string inputs can cause array data structures to be created causing an out of memory panic. Applications that use the _strvals_ package in the Helm SDK to parse user supplied input can suffer a Denial of Service when that input causes a panic that cannot be recovered from. The Helm Client will panic with input to `--set`, `--set-string`, and other value setting flags that causes an out of memory panic. Helm is not a long running service so the panic will not affect future uses of the Helm client. This issue has been resolved in 3.9.4. SDK users can validate strings supplied by users won't create large a...

### Impact NVFLARE contains a vulnerability where deserialization of Untrusted Data due to Pickle usage may allow an unprivileged network attacker to cause Remote Code Execution, Denial Of Service, and Impact to both Confidentiality and Integrity. All versions before 2.1.4 are affected. CVSS Score = 9.8 [AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H](https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) ### Patches The patch is included in nvflare==2.1.4 This new version uses MessagePack instead of Pickle to do serialization and deserialization. Some object serializations supported by Pickle are not supported by MessagePack. We have provided out of box support for some built-in NVFLARE objects. For object serializations unsupported by MessagePack, the user will need to convert the objects to numpy or bytes before sending over to remote machines. The list of supported object types are listed in https://github.com/NVIDIA/NV...

### Impact Possible ReDoS with lib input of `{{` and with many repetitions of `{{|`. ### Patches Patched in all versions above `0.2.5` ### Workarounds No known work arounds. ### References - OWASP: [Regular expression Denial of Service - ReDoS](https://www.owasp.org/index.php/Regular_expression_Denial_of_Service_-_ReDoS) - Wikipedia: [ReDoS](https://en.wikipedia.org/wiki/ReDoS). - Wikipedia: [Time complexity](https://en.wikipedia.org/wiki/Time_complexity). - James Kirrage, Asiri Rathnayake, Hayo Thielecke: [Static Analysis for Regular Expression Denial-of-Service Attack](http://www.cs.bham.ac.uk/~hxt/research/reg-exp-sec.pdf). - Common Weakness Enumeration: [CWE-1333](https://cwe.mitre.org/data/definitions/1333.html). - Common Weakness Enumeration: [CWE-400](https://cwe.mitre.org/data/definitions/400.html).

### Impact The Matrix specification specifies a list of [event authorization rules](https://spec.matrix.org/v1.3/rooms/v10/#authorization-rules) which must be checked when determining if an event should be accepted into a room. In versions of Synapse up to and including v1.61, some of these rules are not correctly applied. An attacker could craft events which would be accepted by Synapse but not a spec-conformant server, potentially causing divergence in the room state between servers. ### Patches Administrators of homeservers with federation enabled are advised to upgrade to v1.62.0 or higher. ### Workarounds * Federation can be disabled by setting [`federation_domain_whitelist`](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#federation_domain_whitelist) to an empty list (`[]`). ### References * https://github.com/matrix-org/synapse/pull/13087 * https://github.com/matrix-org/synapse/pull/13088 ### For more information If you have...
