USN-5855-3: ImageMagick regression

Severity

Unknown

Vendor

Canonical Ubuntu

Description

USN-5855-2 fixed vulnerabilities in ImageMagick. Unfortunately an additional mitigation caused a regression. This update fixes the problem. We apologize for the inconvenience. Original advisory details: It was discovered that ImageMagick incorrectly handled certain PNG images. If a user or automated system were tricked into opening a specially crafted PNG file, an attacker could use this issue to cause ImageMagick to stop responding, resulting in a denial of service, or possibly obtain the contents of arbitrary files by including them into images. Update Instructions: Run `sudo pro fix USN-5855-3` to fix the vulnerability. The problem can be corrected by updating your system to the following package versions: libmagick++-6.q16hdri-dev – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickcore-6.q16-6-extra – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickwand-dev – 8:6.9.10.23+dfsg-2.1ubuntu11.7 imagemagick-6.q16 – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickcore-6-headers – 8:6.9.10.23+dfsg-2.1ubuntu11.7 imagemagick-6-common – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickwand-6.q16-6 – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickcore-6.q16hdri-6-extra – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagick++-6-headers – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libimage-magick-q16-perl – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libimage-magick-perl – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagick++-dev – 8:6.9.10.23+dfsg-2.1ubuntu11.7 perlmagick – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickcore-6.q16-6 – 8:6.9.10.23+dfsg-2.1ubuntu11.7 imagemagick – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickwand-6.q16hdri-dev – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickwand-6.q16-dev – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagick++-6.q16hdri-8 – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickcore-6.q16hdri-dev – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagick++-6.q16-dev – 8:6.9.10.23+dfsg-2.1ubuntu11.7 imagemagick-common – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickcore-6.q16-dev – 8:6.9.10.23+dfsg-2.1ubuntu11.7 imagemagick-doc – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagick++-6.q16-8 – 8:6.9.10.23+dfsg-2.1ubuntu11.7 imagemagick-6-doc – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickcore-6.q16hdri-6 – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libimage-magick-q16hdri-perl – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickcore-6-arch-config – 8:6.9.10.23+dfsg-2.1ubuntu11.7 imagemagick-6.q16hdri – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickcore-dev – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickwand-6-headers – 8:6.9.10.23+dfsg-2.1ubuntu11.7 libmagickwand-6.q16hdri-6 – 8:6.9.10.23+dfsg-2.1ubuntu11.7 No subscription required
