Xenstore: Guests can crash xenstored Due to a bug in the fix of XSA-115 a malicious guest can cause xenstored to use a wrong pointer during node creation in an error path, resulting in a crash of xenstored or a memory corruption in xenstored causing further damage. Entering the error path can be controlled by the guest e.g. by exceeding the quota value of maximum nodes per domain.

Xenstore: guests can let run xenstored out of memory T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: - - by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory - - by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path - - by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible - - by accessing many nodes inside a transaction

While fewer cloud providers are suffering outages, customers should prepare for the uncommon event, especially when relying on cloud services for security.

A flaw was found in Ansible in the amazon.aws collection when using the tower_callback parameter from the amazon.aws.ec2_instance module. This flaw allows an attacker to take advantage of this issue as the module is handling the parameter insecurely, leading to the password leaking in the logs.

Multiple command injection vulnerabilities in GL.iNet GoodCloud IoT Device Management System Version 1.00.220412.00 via the ping and traceroute tools allow attackers to read arbitrary files on the system.

Ubuntu Security Notice 5700-1 - David Bouman and Billy Jheng Bing Jhong discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Soenke Huster discovered that an integer overflow vulnerability existed in the WiFi driver stack in the Linux kernel, leading to a buffer overflow. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code.

PRTG Network Monitor through 22.2.77.2204 does not prevent custom input for a device’s icon, which can be modified to insert arbitrary content into the style tag for that device. When the device page loads, the arbitrary Cascading Style Sheets (CSS) data is inserted into the style tag, loading malicious content. Due to PRTG Network Monitor preventing “characters, and from modern browsers disabling JavaScript support in style tags, this vulnerability could not be escalated into a Cross-Site Scripting vulnerability.

Container and Kubernetes adoption brings the promise of faster application development and delivery at larger scales -- however, it also brings with it new security challenges. Protecting cloud-native applications can require significant changes in how organizations approach IT security. They need to apply controls earlier in the application development lifecycle, use existing infrastructure to apply and enforce these controls, keep up with increasingly rapid release schedules, and more.
