Описание
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.
A heap buffer overflow vulnerability exists in ImageMagick and Magick.NET's FTXT encoder due to missing boundary checks for the ftxt:format parameter. A remote attacker could exploit this using a specially crafted FTXT image to cause a denial of service or disclose sensitive information.
Отчет
This low-impact heap buffer overflow in ImageMagick's FTXT encoder, caused by insufficient boundary checks, could lead to denial of service or information disclosure if a user opens a specially crafted FTXT file.
Меры по смягчению последствий
To mitigate this, disable the vulnerable FTXT format by adding the following line to your ImageMagick security policy file (typically /etc/ImageMagick-7/policy.xml): Applying this mitigation will immediately block ImageMagick from processing any files in the FTXT format, but requires no service restarts or downtime.
