The Ubuntu Security Notice USN-2133-1 addresses critical weaknesses in the Linux Kernel, which could lead to system crashes across multiple distributions
ImageMagick could be made to crash or run programs if it opened a specially crafted image file.

Summary

ImageMagick could be made to crash or run programs if it opened a specially

crafted image file.

Software Description:

- imagemagick: Image manipulation programs and library

Details:

Aleksis Kauppinen, Joonas Kuorilehto and Tuomas Parttimaa discovered that

ImageMagick incorrectly handled certain restart markers in JPEG images. If

a user or automated system using ImageMagick were tricked into opening a

specially crafted JPEG image, an attacker could exploit this to cause

memory consumption, resulting in a denial of service. This issue only

affected Ubuntu 12.04 LTS. (CVE-2012-0260)

It was discovered that ImageMagick incorrectly handled decoding certain PSD

images. If a user or automated system using ImageMagick were tricked into

opening a specially crafted PSD image, an attacker could exploit this to

cause a denial of service or possibly execute code with the privileges of

the user invoking the program. (CVE-2014-1958, CVE-2014-2030)
