- CWE-835
Description
image-size through 2.0.2 contains a denial of service vulnerability that allows remote attackers to permanently block the Node.js event loop by supplying a specially crafted image buffer with a zero-valued size field in a recognized box-type. Attackers can trigger an infinite loop in the JXL or HEIF image parsers by providing a crafted image containing a box with a size of zero, causing the offset to never advance and permanently hanging the application.
Affected configurations
• image-size image-size (>= 1.1.0 <= 1.2.1)
• image-size image-size (>= 2.0.0 <= 2.0.2)
