Summary
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. A remote attacker could exploit a vulnerability in the BGR decoder by providing a specially crafted image file.
This flaw, caused by a missing end-of-file check, can lead to a heap buffer over-read, potentially resulting in the disclosure of sensitive information. Moderate: ImageMagick's BGR decoder is vulnerable to a heap buffer over-read when processing specially crafted image files.
This flaw could lead to information disclosure if applications using ImageMagick process untrusted images, potentially exposing sensitive memory contents. The impact is limited to information disclosure and does not directly enable arbitrary code execution.
Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N). Weakness: CWE-125.
Affected Red Hat products: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7.
Red Hat does not currently list a fixing RHSA for this CVE.
Affected products named by the advisory: Red Hat package: imagemagick.
