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.

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)

Specially crafted files could cause overflows 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)

It was found that ImageMagick utilities tried to load ImageMagick configuration files from the current working directory. If a user ran an ImageMagick utility in an attacker-controlled directory containing a specially crafted ImageMagick configuration file, it could cause the utility to execute arbitrary code. (CVE-2010-4167)

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 remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2012-0544 advisory.

    - Add fix for CVE-2010-4167
    - Add fix for CVE-2012-0247 CVE-2012-0248 CVE-2012-1185 CVE-2012-1186

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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 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.

ImageMagick reports :

Three vulnerabilities have been identified in ImageMagick's handling of JPEG and TIFF files. With these vulnerabilities, it is possible to cause a denial of service situation in the target system.

The remote Windows host is running a version of ImageMagick earlier than 6.7.6-3 and is, therefore, affected by the following vulnerabilities :

  - An error exists in the function 'GetEXIFProperty' in     the file 'magick/property.c' that can cause the     application to crash when processing JPEG 'EXIF' data.
    (CVE-2012-0259)

  - An error exists in the function 'JPEGWarningHandler' in     the file 'coders/jpeg.c' that can cause the application     to consume large amounts of resources when handling JPEG     'restart' markers. (CVE-2012-0260)

  - An error exists in the function 'TIFFGetEXIFProperties'     in the file 'coders/tiff.c' that can cause the     application crash when processing TIFF 'EXIF' 'IFD'     data. (CVE-2012-1798)

Multiple vulnerabilities has been found and corrected in imagemagick :
