Ubuntu Security Notice 6300-1 - William Zhao discovered that the Traffic Control subsystem in the Linux kernel did not properly handle network packet retransmission in certain situations. A local attacker could use this to cause a denial of service. It was discovered that the NTFS file system implementation in the Linux kernel did not properly check buffer indexes in certain situations, leading to an out-of-bounds read vulnerability. A local attacker could possibly use this to expose sensitive information.

While IT security managers in companies and public administrations rely on the concept of Zero Trust, APTS (Advanced Persistent Threats) are putting its practical effectiveness to the test. Analysts, on the other hand, understand that Zero Trust can only be achieved with comprehensive insight into one's own network.  Just recently, an attack believed to be perpetrated by the Chinese hacker group

You've probably never heard of "16Shop," but there's a good chance someone using it has tried to phish you. Last week, the international police organization INTERPOL said it had shuttered the notorious 16Shop, a popular phishing-as-a-service platform launched in 2017 that made it simple for even complete novices to conduct complex and convincing phishing scams. INTERPOL said authorities in Indonesia arrested the 21-year-old proprietor and one of his alleged facilitators, and that a third suspect was apprehended in Japan.

rubygems.org is the Ruby community's primary gem (library) hosting service. Insufficient input validation allowed malicious actors to replace any uploaded gem version that had a platform, version number, or gem name matching `/-\d/`, permanently replacing the legitimate upload in the canonical gem storage bucket, and triggering an immediate CDN purge so that the malicious gem would be served immediately. The maintainers have checked all gems matching the `/-\d/` pattern and can confirm that no unexpected `.gem`s were found. As a result, we believe this vulnerability was _not_ exploited. The easiest way to ensure that a user's applications were not exploited by this vulnerability is to check that all of your downloaded .gems have a checksum that matches the checksum recorded in the RubyGems.org database. RubyGems contributor Maciej Mensfeld wrote a tool to automatically check that all downloaded .gem files match the checksums recorded in the RubyGems.org database. You can use it by runn...

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user who can view `Invitation.WebHome` can execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. This vulnerability has been patched on XWiki 14.4.8, 15.2-rc-1, and 14.10.6. Users are advised to upgrade. Users unable to upgrade may manually apply the patch on `Invitation.InvitationCommon` and `Invitation.InvitationConfig`, but there are otherwise no known workarounds for this vulnerability.

A previously undetected attack method called NoFilter has been found to abuse the Windows Filtering Platform (WFP) to achieve privilege escalation in the Windows operating system. "If an attacker has the ability to execute code with admin privilege and the target is to perform LSASS Shtinkering, these privileges are not enough," Ron Ben Yizhak, a security researcher at Deep Instinct, told The

A new, financially motivated operation dubbed LABRAT has been observed weaponizing a now-patched critical flaw in GitLab as part of a cryptojacking and proxyjacking campaign. "The attacker utilized undetected signature-based tools, sophisticated and stealthy cross-platform malware, command-and-control (C2) tools which bypassed firewalls, and kernel-based rootkits to hide their presence," Sysdig

A vulnerability in the filesystem image parser for Hierarchical File System Plus (HFS+) of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to an incorrect check for completion when a file is decompressed, which may result in a loop condition that could cause the affected software to stop responding. An attacker could exploit this vulnerability by submitting a crafted HFS+ filesystem image to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to stop responding, resulting in a DoS condition on the affected software and consuming available system resources. For a description of this vulnerability, see the ClamAV blog .
