Ubuntu Security Notice 6541-2 - USN-6541-1 fixed vulnerabilities in the GNU C Library. Unfortunately, changes made to allow proper application of the fix for CVE-2023-4806 in Ubuntu 22.04 LTS introduced an issue in the NSCD service IPv6 processing functionalities. This update fixes the problem.

Gentoo Linux Security Advisory 202401-14 - A denial of service vulnerability has been found in RedCloth. Versions greater than or equal to 4.3.2-r5 are affected.

Gentoo Linux Security Advisory 202401-13 - Multiple denial of service vulnerabilities have been found in FAAD2. Versions greater than or equal to 2.11.0 are affected.

PSOProxy version 0.5 suffers from a denial of service vulnerability.

Ubuntu Security Notice 6573-1 - Lucas Leong discovered that the netfilter subsystem in the Linux kernel did not properly validate some attributes passed from userspace. A local attacker could use this to cause a denial of service or possibly expose sensitive information. Kyle Zeng discovered that the IPv4 implementation in the Linux kernel did not properly handle socket buffers when performing IP routing in certain circumstances, leading to a null pointer dereference vulnerability. A privileged attacker could use this to cause a denial of service.

Ubuntu Security Notice 6572-1 - Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero erasesize during device attachment. A local privileged attacker could use this to cause a denial of service. Bien Pham discovered that the netfiler subsystem in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local user could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6548-4 - It was discovered that Spectre-BHB mitigations were missing for Ampere processors. A local attacker could potentially use this to expose sensitive information. It was discovered that the USB subsystem in the Linux kernel contained a race condition while handling device descriptors in certain situations, leading to a out-of-bounds read vulnerability. A local attacker could possibly use this to cause a denial of service.

Red Hat Security Advisory 2024-0050-03 - Red Hat OpenShift Container Platform release 4.14.8 is now available with updates to packages and images that fix several bugs and add enhancements. Issues addressed include a denial of service vulnerability.

# Microsoft Security Advisory CVE-2024-21319: .NET Denial of Service Vulnerability ## <a name="executive-summary"></a>Executive summary Microsoft is releasing this security advisory to provide information about a vulnerability in the ASP.NET Core project templates. This advisory also provides guidance on what developers can do to update their applications to address this vulnerability. A Denial of Service vulnerability exists in ASP.NET Core project templates which utilize JWT-based authentication tokens. This vulnerability allows an unauthenticated client to consume arbitrarily large amounts of server memory, potentially triggering an out-of-memory condition on the server and making the server no longer able to respond to legitimate requests. ## Announcement Announcement for this issue can be found at https://github.com/dotnet/announcements/issues/290 ### <a name="mitigation-factors"></a>Mitigation factors This impacts only .NET Core-based projects that were created using any...

### Impact _What kind of vulnerability is it? Who is impacted?_ An attacker could exploit this vulnerability by crafting a malicious JSON Web Encryption (JWE) token with a high compression ratio. This token, when processed by a server, leads to excessive memory allocation and processing time during decompression, causing a denial-of-service (DoS) condition. It's important to note that the attacker must have access to the public encrypt key registered with the IDP(Entra ID) for successful exploitation. _According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?_ A scope change (S:C) in the CVSS metric indicates that successful exploitation of this vulnerability could extend beyond the immediate processing of malicious tokens, affecting the overall availability of the system by causing a denial-of-service (DoS) condition. ### Patches _Has the problem been patched? What versions should users upgrade to?_ The v...
