Dear LinuxPatch Readers,
Today, we are dissecting a critical vulnerability identified in one of the widely used open-source tools, ImageMagick. For those unfamiliar, ImageMagick is a robust tool used for creating, editing, composing, or converting digital images. It can read and write a variety of formats (over 200) including PNG, JPEG, GIF, HEIC, TIFF, DPX, EXR, WebP, Postscript, PDF, and SVG. However, like any software, it's not without its flaws.
The issue at hand is CVE-2017-13144, which was flagged with a severity rating of MEDIUM and a CVSS (Common Vulnerability Scoring System) score of 6.5. This vulnerability is associated with a flaw in ImageMagick version 6.9.7-9 and earlier.
Issue Description:
In ImageMagick before 6.9.7-10, there is a potential system crash when trying to process images with exceedingly high dimensions. Rather than throwing an error message indicating that 'width or height exceeds limit', the software experiences a crash. This crash is specifically triggered by the use of the mpc coder, which can be exploited by someone maliciously crafting an image file with extremely large dimensions, thereby causing denial of service through application crash.
Impact on Your Systems:
This vulnerability primarily affects systems where ImageMagick is used to process images. Systems without adequate security checks on image sizes could inadvertently run into service disruptions, directly impacting services reliant on ImageMagick. In a broader sense, any downtime or service disruption can decrease productivity, affect service delivery, and compromise data integrity.
What Should You Do?
It is imperative for administrators and software engineers to patch this vulnerability in their ImageMagick installations to prevent any potential explotation. Ensuring your system is updated to ImageMagick 6.9.7-10 or later, which contain the fixes for this issue, is the most straightforward form of mitigation.
At LinuxPatch, we simplifiy the patch management process. Integrating our solutions can ensure that your Linux systems are automatically updated with the latest security patches, including updates for ImageMagick.
