Packet Storm

Ubuntu Security Notice 5732-1 - It was discovered that Unbound incorrectly handled delegations with a large number of non-responsive nameservers. A remote attacker could possibly use this issue to cause Unbound to consume resources, leading to a denial of service.

Debian Linux Security Advisory 5284-1 - Multiple security issues were discovered in Thunderbird, which could result in denial of service or the execution of arbitrary code.

Red Hat Security Advisory 2022-8524-01 - Red Hat Data Grid is an in-memory, distributed, NoSQL datastore solution. It increases application response times and allows for dramatically improving performance while providing availability, reliability, and elastic scale. Data Grid 8.4.0 replaces Data Grid 8.3.1 and includes bug fixes and enhancements. Find out more about Data Grid 8.4.0 in the Release Notes[3]. Issues addressed include cross site scripting and denial of service vulnerabilities.

Red Hat Security Advisory 2022-8532-01 - Red Hat Satellite is a system management solution that allows organizations to configure and maintain their systems without the necessity to provide public Internet access to their servers or other client systems. It performs provisioning and configuration management of predefined standard operating environments. Issues addressed include a HTTP request smuggling vulnerability.

Ubuntu Security Notice 5638-2 - USN-5638-1 fixed a vulnerability in Expat. This update provides the corresponding updates for Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. Rhodri James discovered that Expat incorrectly handled memory when processing certain malformed XML files. An attacker could possibly use this issue to cause a crash or execute arbitrary code.

Ubuntu Security Notice 5730-1 - Several security issues were discovered in the WebKitGTK Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.

Ubuntu Security Notice 5731-1 - It was discovered that multipath-tools incorrectly handled symlinks. A local attacker could possibly use this issue, in combination with other issues, to escalate privileges. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 22.10. It was discovered that multipath-tools incorrectly handled access controls. A local attacker could possibly use this issue, in combination with other issues, to escalate privileges.

PatrIoT provides a four-stage IoT vulnerability research methodology built on top of four key elements: logical attack surface decomposition, compilation of top 100 weaknesses, lightweight risk scoring, and step-by-step penetration testing guidelines. The proposed methodology is evaluated with multiple IoT products. The results indicate that PatrIoT allows cyber security practitioners without much experience to advance vulnerability research activities quickly and reduces the risk of critical IoT penetration testing steps being overlooked.

In the function AppleAVDUserClient::decodeFrameFig, a location in the decoder's IOSurface input buffer is calculated, and then bzero is called on it. The size of this IOSurface's allocation is controllable by the userspace caller, so the calculated pointer can go out of bounds, leading to memory corruption. This issue could potentially allow an unprivileged local application to escalate its privileges to the kernel.

In AppleAVD.kext, pixel buffers are mapped by calling AppleAVDUserClient::_mapPixelBuffer, which eventually calls AppleAVD::allocateKernelMemoryInternal. If the buffer is an IOSurface, the function calls IOSurface::deviceLockSurface before allocating memory by calling prepare. But when a pixel buffer is unmapped by calling AppleAVDUserClient::_unmapPixelBuffer, which calls AppleAVD::deallocateKernelMemoryInternal, the IOSurface is not locked before calling complete. This means that mapping and unmapping can occur at the same time, leading to kernel memory corruption. This bug could allow escalation to kernel privileges from a local app.
