18-Byte ImageMagick Hack Could Have Leaked Images From Yahoo Mail Server

18-Byte ImageMagick Hack Could Have Leaked Images From Yahoo Mail Server

May 23, 2017
After the discovery of a critical vulnerability that could have allowed hackers to view private Yahoo Mail images, Yahoo retired the image-processing library ImageMagick. ImageMagick is an open-source image processing library that lets users resize, scale, crop, watermarking and tweak images. The tool is supported by PHP, Python, Ruby, Perl, C++, and many other programming languages. This popular image-processing library made headline last year with the discovery of the then-zero-day vulnerability, dubbed ImageTragick , which allowed hackers to execute malicious code on a Web server by uploading a maliciously-crafted image. Now, just last week, security researcher Chris Evans demonstrated an 18-byte exploit to the public that could be used to cause Yahoo servers to leak other users' private Yahoo! Mail image attachments. 'Yahoobleed' Bug Leaks Images From Server Memory The exploit abuses a security vulnerability in the ImageMagick library, which Evans dubbed

Warning — Widely Popular ImageMagick Tool Vulnerable to Remote Code Execution

May 04, 2016
A serious zero-day vulnerability has been discovered in ImageMagick , a widely popular software tool used by a large number of websites to process user's photos, which could allow hackers to execute malicious code remotely on servers. ImageMagick is an open-source image processing library that lets users resize, scale, crop, watermarking and tweak images. The ImageMagick tool is supported by many programming languages, including Perl, C++, PHP, Python, Ruby and is being deployed by Millions of websites, blogs, social media platforms, and popular content management systems (CMS) such as WordPress and Drupal. Slack security engineer Ryan Huber disclosed a zero-day flaw (CVE-2016–3714) in the ImageMagick image processing library that allows a hacker to execute malicious code on a Web server by uploading maliciously-crafted image. For example, by uploading a booby-trapped selfie to a web service that uses ImageMagick, an attacker can execute malicious code on the website&#
How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

Mar 21, 2024SaaS Security / Endpoint Security
In today's digital-first business environment dominated by SaaS applications, organizations increasingly depend on third-party vendors for essential cloud services and software solutions. As more vendors and services are added to the mix, the complexity and potential vulnerabilities within the  SaaS supply chain  snowball quickly. That's why effective vendor risk management (VRM) is a critical strategy in identifying, assessing, and mitigating risks to protect organizational assets and data integrity. Meanwhile, common approaches to vendor risk assessments are too slow and static for the modern world of SaaS. Most organizations have simply adapted their legacy evaluation techniques for on-premise software to apply to SaaS providers. This not only creates massive bottlenecks, but also causes organizations to inadvertently accept far too much risk. To effectively adapt to the realities of modern work, two major aspects need to change: the timeline of initial assessment must shorte
