At Cloudflare, we're constantly vigilant when it comes to identifying vulnerabilities that could potentially affect the Internet ecosystem. Recently, on September 12, 2023, Google announced a security issue in Google Chrome, titled "Heap buffer overflow in WebP in Google Chrome," which caught our attention. Initially, it seemed like just another bug in the popular web browser. However, what we discovered was far more significant and had implications that extended well beyond Chrome.

Recently, Qualys discovered and reported a critical vulnerability affecting the popular GLIBC ecosystem, which is installed by default on most Linux-based operating systems. Specifically, a buffer overflow was found in the code responsible for handling special environment variables during the startup of a process which can result in a local privilege escalation. Fortunately, exploitation of this vulnerability can be detected by Falco.

The developer role is steadily expanding, now encompassing operations and security functions in addition to writing and testing code.

Last month, two Critical vulnerabilities (CVE-2023-4863 and CVE-2023-5129) were identified by Apple Security Engineering and Architecture (SEA) in collaboration with The Citizen Lab at the University of Toronto’s Munk School. The vulnerabilities involved maliciously formed WebP images that would exploit Chromium-based browsers and the webmproject/libwebp library provided by Google. You can learn more about the vulnerability and the recent history of it in our previous blog post.

The cloud revolution has firmly taken hold, and businesses of all sizes are adopting cloud-native technologies. This new paradigm has also created newer attack surfaces for cybercriminals, who are eager to exploit known security gaps in cloud environments. Sysdig is collaborating with Docker to deliver a more efficient process for identifying risks and opportunities for accelerated remediation in Docker Scout using runtime insights.

In the tech security scene, we’re always on the lookout for new vulnerabilities, especially when they are already exploited in the wild. The latest zero-day CVE-2023-20269 is hitting Cisco’s Adaptive Security Appliance VPN features. The attack surface scan conducted by IONIX research on a sample of organizations indicates that 13% of these appliances are potentially vulnerable through at least one interface.

On 2023-10-04 at 13:00 UTC, Atlassian released details of the zero-day vulnerability described as “Privilege Escalation Vulnerability in Confluence Data Center and Server” (CVE-2023-22515), a zero-day vulnerability impacting Confluence Server and Data Center products. Cloudflare was warned about the vulnerability before the advisory was published and worked with Atlassian to proactively apply protective WAF rules for all customers.

Snyk has been a long-time active participant in and sponsor of the Open Source Security Foundation (OpenSSF). We’re there because we believe in supporting its mission of securing the open source ecosystem. A recent summit meeting convened by the OpenSSF with the White House brought together various US Government departments for a chat about open source security.

On October 3, 2023, Daniel Stenberg, the long-time curl maintainer and original author, published a note on both LinkedIn and X (formerly Twitter) regarding the shipping of curl version 8.4.0, which will contain a fix for "probably the worst security problem found in curl in a long time." This issue should be taken seriously as curl maintainers have been vocal about downplaying the risk associated with most vulnerabilities reported against curl in the past (a recent example is the article CVE-2020-1990

The infostealer malware Rhadamanthys was discovered in the last quarter of 2022. Its capabilities showed a special interest in crypto currency wallets, targeting both wallet clients installed in the victim’s machine and browser extensions. The main distribution methods observed for this threat are fake software websites promoted through Google Ads, and phishing emails, without discriminating by region or vertical.
