AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

ImageMagick processes a crafted file causing undefined behavior due to values outside unsigned long range, leading to application availability impact.

Vulnerability

A flaw in ImageMagick versions prior to 7.0.9-0, specifically in MagickCore/statistic.c, allows an attacker to submit a crafted file that, when processed, triggers undefined behavior due to values outside the range of type unsigned long [1].

Exploitation

An attacker can exploit this vulnerability by providing a specially crafted file to ImageMagick for processing. No special privileges or network position are mentioned; file processing is a common operation, so user interaction (e.g., opening the file) is required [1].

Impact

The undefined behavior most likely leads to an impact on application availability, but could potentially cause other problems related to undefined behavior [1]. No other CIA impacts are disclosed.

Mitigation

The fix is included in ImageMagick version 7.0.9-0 and later. For Red Hat Enterprise Linux 5, 6, and 7, this flaw is out of support scope. Inkscape in RHEL8 is not affected because it no longer uses a bundled ImageMagick [1].
