Ubuntu Security Notice 6766-1 - It was discovered that the Open vSwitch implementation in the Linux kernel could overflow its stack during recursive action operations under certain conditions. A local attacker could use this to cause a denial of service. Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida discovered that the Linux kernel mitigations for the initial Branch History Injection vulnerability were insufficient for Intel processors. A local attacker could potentially use this to expose sensitive information.

Cybercriminals are vipers. They’re like snakes in the grass, hiding behind their keyboards, waiting to strike. And if you're a small- and medium-sized business (SMB), your organization is the ideal lair for these serpents to slither into.  With cybercriminals becoming more sophisticated, SMBs like you must do more to protect themselves. But at what price? That’s the daunting question

Red Hat Security Advisory 2024-2394-03 - An update for kernel is now available for Red Hat Enterprise Linux 9. Issues addressed include code execution, double free, integer overflow, memory exhaustion, memory leak, null pointer, out of bounds access, out of bounds read, out of bounds write, privilege escalation, and use-after-free vulnerabilities.

Within BEC attacks, adversaries will send phishing emails appearing to be from a known or reputable source making a valid request, such as updating payroll direct deposit information.

Red Hat Security Advisory 2024-2004-03 - An update for kernel is now available for Red Hat Enterprise Linux 7. Issues addressed include null pointer and use-after-free vulnerabilities.

pgAdmin versions 8.3 and below have a path traversal vulnerability within their session management logic that can allow a pickled file to be loaded from an arbitrary location. This can be used to load a malicious, serialized Python object to execute code within the context of the target application. This exploit supports two techniques by which the payload can be loaded, depending on whether or not credentials are specified. If valid credentials are provided, Metasploit will login to pgAdmin and upload a payload object using pgAdmin's file management plugin. Once uploaded, this payload is executed via the path traversal before being deleted using the file management plugin. This technique works for both Linux and Windows targets. If no credentials are provided, Metasploit will start an SMB server and attempt to trigger loading the payload via a UNC path. This technique only works for Windows targets. For Windows 10 v1709 (Redstone 3) and later, it also requires that insecure outbound g...

Ubuntu Security Notice 6725-2 - Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel did not properly validate certain data structure fields when parsing lease contexts, leading to an out-of-bounds read vulnerability. A remote attacker could use this to cause a denial of service or possibly expose sensitive information. Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel, leading to a use-after-free vulnerability. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code.
