CVE-2017-13776

CVE-2017-13776 is a denial-of-service vulnerability in GraphicsMagick 1.3.26, specifically within the ReadXBMImage() function, affecting Debian Linux and GraphicsMagick installations. An attacker can exploit this by crafting a malicious XBM image file, leading to excessive CPU and memory consumption without explicit requests from the file itself. Rated as Medium severity (CVSS 6.5), it requires user interaction (UI:R) to open the malicious file, but the attack complexity is low (AC:L) and can result in high availability impact (A:H). There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion beyond a single mention.
