Multiple integer overflows in (1) magick/profile.c or (2) magick/property.c in ImageMagick 6.7.5 and earlier allow remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code via crafted offset value in the ResolutionUnit tag in the EXIF IFD0 of an image. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-0247.

Specially crafted files could cause overflows in ImageMagick

The remote host is affected by the vulnerability described in GLSA-201405-09 (ImageMagick: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in ImageMagick. Please       review the CVE identifiers referenced below for details.
    Note that CVE-2012-1185 and CVE-2012-1186 were issued due to incomplete       fixes for CVE-2012-0247 and CVE-2012-0248, respectively. The earlier CVEs       were addressed in GLSA 201203-09.
  Impact :

    A remote attacker can utilize multiple vectors to execute arbitrary code       or cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

This update of ImageMagick fixes multiple security vulnerabilities that could be 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)

  - Copying of invalid memory when reading TIFF EXIF IFD.
    (CVE-2012-1798)

Multiple vulnerabilities has been found and corrected in imagemagick :

A flaw was found in the way ImageMagick processed images with malformed Exchangeable image file format (Exif) metadata. An attacker could create a specially crafted image file that, when opened by a victim, would cause ImageMagick to crash or, potentially, execute arbitrary code (CVE-2012-0247).

A denial of service flaw was found in the way ImageMagick processed images with malformed Exif metadata. An attacker could create a specially crafted image file that, when opened by a victim, could cause ImageMagick to enter an infinite loop (CVE-2012-0248).

The original fix for CVE-2012-0247 failed to check for the possibility of an integer overflow when computing the sum of number_bytes and offset. This resulted in a wrap around into a value smaller than length, making original CVE-2012-0247 introduced length check still to be possible to bypass, leading to memory corruption (CVE-2012-1185).

An integer overflow flaw was found in the way ImageMagick processed certain Exif tags with a large components count. An attacker could create a specially crafted image file that, when opened by a victim, could cause ImageMagick to access invalid memory and crash (CVE-2012-0259).

A denial of service flaw was found in the way ImageMagick decoded certain JPEG images. A remote attacker could provide a JPEG image with specially crafted sequences of RST0 up to RST7 restart markers (used to indicate the input stream to be corrupted), which once processed by ImageMagick, would cause it to consume excessive amounts of memory and CPU time (CVE-2012-0260).

An out-of-bounds buffer read flaw was found in the way ImageMagick processed certain TIFF image files. A remote attacker could provide a TIFF image with a specially crafted Exif IFD value (the set of tags for recording Exif-specific attribute information), which once opened by ImageMagick, would cause it to crash (CVE-2012-1798).

The updated packages have been patched to correct these issues.

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 6.7.5-8 and is, therefore, affected by the following vulnerabilities :

  - The fix for CVE-2012-0247 was incomplete. An integer     overflow error still exists and can lead to corrupted     memory and arbitrary code execution when user-supplied     input is not properly validated. (CVE-2012-1185)

  - The fix for CVE-2012-0248 was incomplete. An error in     'profile.c' still allows denial of service attacks when     malformed executables are processed. (CVE-2012-1186)

Multiple vulnerabilities has been found and corrected in imagemagick :

Untrusted search path vulnerability in configure.c in ImageMagick before 6.6.5-5, when MAGICKCORE_INSTALLED_SUPPORT is defined, allows local users to gain privileges via a Trojan horse configuration file in the current working directory (CVE-2010-4167).

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)

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.
