Detailsinfo

A vulnerability, which was classified as critical, has been found in ImageMagick up to 7.1.2-26. This issue affects an unknown code of the component BGR decoder. The manipulation with an unknown input leads to a heap-based overflow vulnerability. Using CWE to declare the problem leads to CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to 7.1.2-27, the BGR decoder does not check for an end-of-file in every location so a crafted image could result in an heap buffer over-read. This issue has been fixed in version 7.1.2-27.
