Ubuntu Security Notice 6890-1 - Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. It was discovered that Firefox did not properly manage certain memory operations in the NSS. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code.

Ubuntu Security Notice 6889-1 - It was discovered that .NET did not properly handle object deserialization. An attacker could possibly use this issue to cause a denial of service. Radek Zikmund discovered that .NET did not properly manage memory. An attacker could use this issue to cause a denial of service or possibly execute arbitrary code. It was discovered that .NET did not properly parse X.509 Content and ObjectIdentifiers. An attacker could possibly use this issue to cause a denial of service.

Red Hat Security Advisory 2024-4430-03 - An update for perl-HTTP-Tiny is now available for Red Hat Enterprise Linux 9.2 Extended Update Support.

### Summary An issue in the OpenSearch observability plugins allows unintended access to private tenant resources like notebooks. The system did not properly check if the user was the resource author when accessing resources in a private tenant, leading to potential data being revealed. ### Impact The lack of proper access control validation for private tenant resources in the OpenSearch observability and reporting plugins can lead to unintended data access. If an authorized user with observability or reporting roles is aware of another user's private tenant resource ID, such as a notebook, they can potentially read, modify, or take ownership of that resource, despite not being the original author, thus impacting the confidentiality and integrity of private tenant resources. The impact is confined to private tenant resources, where authorized users may gain inappropriate visibility into data intended to be private from other users within the same OpenSearch instance, potentially vio...

The Problem The “2024 Attack Intelligence Report” from the staff at Rapid7 [1] is a well-researched, well-written report that is worthy of careful study. Some key takeaways are:  53% of the over 30 new vulnerabilities that were widely exploited in 2023 and at the start of 2024 were zero-days. More mass compromise events arose from zero-day vulnerabilities than from n-day vulnerabilities.

Ubuntu Security Notice 6886-1 - It was discovered that the Go net/http module did not properly handle the requests when request\'s headers exceed MaxHeaderBytes. An attacker could possibly use this issue to cause a panic resulting into a denial of service. This issue only affected Go 1.21 in Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. It was discovered that the Go net/http module did not properly validate the subdomain match or exact match of the initial domain. An attacker could possibly use this issue to read sensitive information. This issue only affected Go 1.21 in Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.

Ubuntu Security Notice 6880-1 - Sam Shahsavar discovered that Apache Tomcat did not properly reject HTTP requests with an invalid Content-Length header. A remote attacker could possibly use this issue to perform HTTP request smuggling attacks.
