A heap-use-after-free flaw was found in ImageMagick's RelinquishDCMInfo() function of dcm.c file. This vulnerability is triggered when an attacker passes a specially crafted DICOM image file to ImageMagick for conversion, potentially leading to information disclosure and a denial of service.
A flaw was found in ImageMagick. The vulnerability occurs due to improper use of open functions and leads to a denial of service. This flaw allows an attacker to crash the system.
ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you may use, copy, modify, and distribute in both open and proprietary applications. In affected versions and in certain cases, Postscript files could be read and written when specifically excluded by a `module` policy in `policy.xml`. ex. <policy domain="module" rights="none" pattern="PS" />. The issue has been resolved in ImageMagick 7.1.0-7 and in 6.9.12-22. Fortunately, in the wild, few users utilize the `module` policy and instead use the `coder` policy that is also our workaround recommendation: <policy domain="coder" rights="none" pattern="{PS,EPI,EPS,EPSF,EPSI}" />.
