Joonas Kuorilehto and Aleksis Kauppinen discovered that ImageMagick incorrectly handled certain ResolutionUnit tags. If a user or automated system using ImageMagick were tricked into opening a specially crafted 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-2012-0247, CVE-2012-1185)

Joonas Kuorilehto and Aleksis Kauppinen discovered that ImageMagick incorrectly handled certain IFD structures. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service.
(CVE-2012-0248, CVE-2012-1186)

Aleksis Kauppinen, Joonas Kuorilehto and Tuomas Parttimaa discovered that ImageMagick incorrectly handled certain JPEG EXIF tags. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service. (CVE-2012-0259)

It was discovered that ImageMagick incorrectly handled certain JPEG EXIF tags. If a user or automated system using ImageMagick were tricked into opening a specially crafted 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-2012-1610)

Aleksis Kauppinen, Joonas Kuorilehto and Tuomas Parttimaa discovered that ImageMagick incorrectly handled certain TIFF EXIF tags. If a user or automated system using ImageMagick were tricked into opening a specially crafted 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-2012-1798).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several integer overflows and missing input validations were discovered in the ImageMagick image manipulation suite, resulting in the execution of arbitrary code or denial of service.

Specially crafted files could cause overflows in ImageMagick

The remote Solaris system is missing necessary patches to address security updates :

  - The GetEXIFProperty function in magick/property.c in     ImageMagick before 6.7.6-3 allows remote attackers to     cause a denial of service (crash) via a zero value in     the component count of an EXIF XResolution tag in a JPEG     file, which triggers an out-of-bounds read.
    (CVE-2012-0259)

  - The JPEGWarningHandler function in coders/jpeg.c in     ImageMagick before 6.7.6-3 allows remote attackers to     cause a denial of service (memory consumption) via a     JPEG image with a crafted sequence of restart markers.
    (CVE-2012-0260)

  - Integer overflow in the GetEXIFProperty function in     magick/property.c in ImageMagick before 6.7.6-4 allows     remote attackers to cause a denial of service     (out-of-bounds read) via a large component count for     certain EXIF tags in a JPEG image. NOTE: this     vulnerability exists because of an incomplete fix for     CVE-2012-0259. (CVE-2012-1610)

  - The TIFFGetEXIFProperties function in coders/tiff.c in     ImageMagick before 6.7.6-3 allows remote attackers to     cause a denial of service (out-of-bounds read and crash)     via a crafted EXIF IFD in a TIFF image. (CVE-2012-1798)

This update of ImageMagick fixes multiple security vulnerabilities that could have been exploited by attackers via specially crafted image files :

  - Integer overflow when processing EXIF directory entries     with tags of e.g. format 5 (EXIF_FMT_URATIONAL) and a     large components count. (CVE-2012-0259 / CVE-2012-1610)

  - Integer overflows via 'number_bytes' and 'offset' could     lead to memory corruption. (CVE-2012-0247 /     CVE-2012-1185)

  - Denial of service via 'profile.c'. (CVE-2012-0248 /     CVE-2012-1186)

  - Denial of service via JPEG restart markers (excessive     CPU consumption). (CVE-2012-0260)

The remote Windows host is running a version of ImageMagick earlier than 6.7.6-4 and is, therefore, affected by a heap-based buffer overflow vulnerability because the fix for CVE-2012-0259 was incomplete.

The functions 'GetEXIFProperty' and 'SyncImageProfiles' in the file 'magick/profile.c' do not properly validate user-supplied input. This error can cause the application to crash when processing certain 'EXIF' data.

  - Denial of service via JPEG restart markers (excessive     CPU consumption). (CVE-2012-0260)

  - Copying of invalid memory when reading TIFF EXIF IFD.
