Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS Summary: Several security issues were fixed in ImageMagick. Software Description: - imagemagick: Image manipulation programs and library Details: Due to a large number of issues discovered in GhostScript that prevent it from being used by ImageMagick safely, this update includes a default policy change that disables support for the Postscript and PDF formats in ImageMagick. This policy can be overridden if necessary by using an alternate ImageMagick policy configuration. It was discovered that several memory leaks existed when handling certain images in ImageMagick. An attacker could use this to cause a denial of service. (CVE-2018-14434, CVE-2018-14435, CVE-2018-14436, CVE-2018-14437, CVE-2018-16640, CVE-2018-16750) It was discovered that ImageMagick did not properly initialize a variable before using it when processing MAT images. An attacker could use this to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 18.04 LTS. (CVE-2018-14551) It was discovered that an information disclosure vulnerability existed in ImageMagick when processing XBM images. An attacker could use this to expose sensitive information. (CVE-2018-16323) It was discovered that an out-of-bounds write vulnerability existed in ImageMagick when handling certain images. An attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2018-16642) It was discovered that ImageMagick did not properly check for errors in some situations. An attacker could use this to cause a denial of service. (CVE-2018-16643) It was discovered that ImageMagick did not properly validate image meta data in some situations. An attacker could use this to cause a denial of service. (CVE-2018-16644) It was discovered that ImageMagick did not prevent excessive memory allocation when handling certain image types. An attacker could use this to cause a denial of service. (CVE-2018-16645) Sergej Schumilo and Cornelius Aschermann discovered that ImageMagick did not properly check for NULL in some situations when processing PNG images. An attacker could use this to cause a denial of service. (CVE-2018-16749) USN-3681-1 fixed vulnerabilities in Imagemagick. Unfortunately, the fix for CVE-2017-13144 introduced a regression in ImageMagick in Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. This update reverts the fix for CVE-2017-13144 for those releases. We apologize for the inconvenience. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: Ubuntu 16.04 LTS: Ubuntu 14.04 LTS: In general, a standard system update will make all the necessary changes.
