Name of the Vulnerable Software and Affected Versions ImageMagick versions prior to 7.0.8-16

Description The issue is related to an infinite loop in the coders/bmp.c component of ImageMagick, which can cause high CPU and memory consumption, leading to a denial of service. Remote attackers can exploit this by using a crafted file.

Recommendations For versions prior to 7.0.8-16, update to version 7.0.8-16 or later to resolve the issue. As a temporary workaround, consider restricting the use of the coders/bmp.c component to minimize the risk of exploitation.
