Ecosystem-wide dependent count for version 2.0.2.

DescriptionCVE.org

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 ICNS image buffer. Attackers can craft an ICNS buffer containing valid magic bytes and a zero-valued entry length field to trigger an infinite loop in the ICNS parser, as the offset is never incremented when the entry length field is 0, causing the while loop condition to remain true indefinitely.

AnalysisAI

Denial of service in the image-size Node.js library (versions up to and including 2.0.2) allows remote unauthenticated attackers to permanently stall the Node.js event loop by submitting a malformed ICNS image. The flaw stems from an infinite loop in the ICNS parser when an entry length field is zero, and publicly available exploit code exists per VulnCheck and an independent write-up; no public exploit identified at time of analysis indicates active exploitation, but the POC makes weaponization trivial.

Technical ContextAI

image-size is a widely used npm package that detects image dimensions and format by parsing image headers, including the Apple Icon Image (ICNS) container format. ICNS files consist of a magic header followed by a series of typed entries, each declaring its own length; the parser walks these entries by advancing an offset using the declared length. CWE-835 (Loop with Unreachable Exit Condition) applies because the ICNS parser uses the entry-length field both as the loop's progress counter and as untrusted input - if an attacker supplies a length of zero, the offset never advances and the while-loop condition (offset < buffer end) remains true forever, blocking the single-threaded Node.js event loop. The affected CPE cpe:2.3:a:image-size:image-size confirms the upstream JavaScript package as the vulnerable component, not a downstream fork.

RemediationAI

Upgrade to the patched release of image-size that incorporates pull request #439 from https://github.com/image-size/image-size/pull/439; an upstream fix is available (PR/commit), but a specific released patched version number is not independently confirmed in the supplied data, so verify the current npm release notes before pinning. As an interim workaround when an immediate upgrade is not possible, reject ICNS inputs at the application boundary (for example, by checking the magic bytes 'icns' and refusing that container type) or enforce a strict allow-list of formats such as PNG/JPEG/WebP - this eliminates the parser path entirely at the cost of dropping legitimate macOS icon uploads. Additionally, run image parsing in a worker thread or child process with a hard wall-clock timeout so a single hung parse cannot take down the main event loop, accepting the modest latency and memory overhead of process isolation. Consult the VulnCheck advisory at https://www.vulncheck.com/advisories/image-size-denial-of-service-via-malformed-icns-image-parsing for additional vendor guidance.
