ImageMagick before 7.1.2-19 contains a heap buffer overflow vulnerability in the FTXT encoder due to missing boundary checks when parsing ftxt:format. Remote attackers can trigger an out of bounds read by crafting malicious FTXT image files to cause denial of service or information disclosure.

There are packages installed that are affected by a vulnerability referenced in the following CVE:
