Description
A flaw was found in ImageMagick, a free and open-source software used for editing and manipulating digital images. A remote attacker, by connecting to a magick -distribute-cache service, can trigger a heap buffer over-write in the server process. This vulnerability can lead to a denial of service (DoS) due to memory corruption, potentially making the service unavailable.
Statement
Moderate: A heap buffer overwrite vulnerability in ImageMagick's magick -distribute-cache service allows a remote, unauthenticated attacker to cause a denial of service. This flaw requires the magick -distribute-cache service to be explicitly enabled and exposed, as it is not enabled by default in Red Hat products, limiting its impact to specific configurations.
