Off-by-one error in the ReadBlobString function in blob.c in ImageMagick before 6.3.5-9 allows context-dependent attackers to execute arbitrary code via a crafted image file, which triggers the writing of a '\0' character to an out-of-bounds address.

Several vulnerabilities have been discovered in the imagemagick image manipulation programs which can lead to the execution of arbitrary code, exposure of sensitive information or cause DoS. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2007-1667     Multiple integer overflows in XInitImage function in     xwd.c for ImageMagick, allow user-assisted remote     attackers to cause a denial of service (crash) or obtain     sensitive information via crafted images with large or     negative values that trigger a buffer overflow. It only     affects the oldstable distribution (etch).

  - CVE-2007-1797     Multiple integer overflows allow remote attackers to     execute arbitrary code via a crafted DCM image, or the     colors or comments field in a crafted XWD image. It only     affects the oldstable distribution (etch).

  - CVE-2007-4985     A crafted image file can trigger an infinite loop in the     ReadDCMImage function or in the ReadXCFImage function.
    It only affects the oldstable distribution (etch).

  - CVE-2007-4986     Multiple integer overflows allow context-dependent     attackers to execute arbitrary code via a crafted .dcm,     .dib, .xbm, .xcf, or .xwd image file, which triggers a     heap-based buffer overflow. It only affects the     oldstable distribution (etch).

  - CVE-2007-4987     Off-by-one error allows context-dependent attackers to     execute arbitrary code via a crafted image file, which     triggers the writing of a '\0' character to an     out-of-bounds address. It affects only the oldstable     distribution (etch).

  - CVE-2007-4988     A sign extension error allows context-dependent     attackers to execute arbitrary code via a crafted width     value in an image file, which triggers an integer     overflow and a heap-based buffer overflow. It affects     only the oldstable distribution (etch).

  - CVE-2008-1096     The load_tile function in the XCF coder allows     user-assisted remote attackers to cause a denial of     service or possibly execute arbitrary code via a crafted     .xcf file that triggers an out-of-bounds heap write. It     affects only to oldstable (etch).

  - CVE-2008-1097     Heap-based buffer overflow in the PCX coder allows     user-assisted remote attackers to cause a denial of     service or possibly execute arbitrary code via a crafted     .pcx file that triggers incorrect memory allocation for     the scanline array, leading to memory corruption. It     affects only to oldstable (etch).

  - CVE-2009-1882     Integer overflow allows remote attackers to cause a     denial of service (crash) and possibly execute arbitrary     code via a crafted TIFF file, which triggers a buffer     overflow.

Multiple vulnerabilities were discovered in the image decoders of ImageMagick. If a user or automated system were tricked into processing malicious DCM, DIB, XBM, XCF, or XWD images, a remote attacker could execute arbitrary code with user privileges.

The updated packages have been patched to correct these issues.

This update of ImageMagick fixes several vulnerabilities.

  - infinite loop while parsing images. (CVE-2007-4985)

  - integer overflows that can lead to code execution.
    (CVE-2007-4986)

  - one-byte buffer overflow that can lead to code execution     (SLES8- and SLES9-based products are not affected).
    (CVE-2007-4987)

  - integer overflows that can lead to code execution.
    (CVE-2007-4988)

Multiple vulnerabilities were found in the image decoders of ImageMagick. If a user or automated system were tricked into processing a malicious DCM, DIB, XBM, XCF, or XWD image, a remote attacker could execute arbitrary code with user privileges.

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.

The remote host is affected by the vulnerability described in GLSA-200710-27 (ImageMagick: Multiple vulnerabilities)

    regenrecht reported multiple infinite loops in functions ReadDCMImage()     and ReadXCFImage() (CVE-2007-4985), multiple integer overflows when     handling certain types of images (CVE-2007-4986, CVE-2007-4988), and an     off-by-one error in the ReadBlobString() function (CVE-2007-4987).
  Impact :

    A remote attacker could entice a user to open a specially crafted     image, possibly resulting in the remote execution of arbitrary code     with the privileges of the user running the application, or an     excessive CPU consumption. Note that applications relying on     ImageMagick to process images can also trigger the vulnerability.
  Workaround :

    There is no known workaround at this time.

Multiple vulnerabilities have been discovered in ImageMagick.

ImageMagick before 6.3.5-9 allows context-dependent attackers to cause a denial of service via a crafted image file that triggers (1) an infinite loop in the ReadDCMImage function, related to ReadBlobByte function calls; or (2) an infinite loop in the ReadXCFImage function, related to ReadBlobMSBLong function calls.

Multiple integer overflows in ImageMagick before 6.3.5-9 allow context-dependent attackers to execute arbitrary code via a crafted (1) .dcm, (2) .dib, (3) .xbm, (4) .xcf, or (5) .xwd image file, which triggers a heap-based buffer overflow.

Off-by-one error in the ReadBlobString function in blob.c in ImageMagick before 6.3.5-9 allows context-dependent attackers to execute arbitrary code via a crafted image file, which triggers the writing of a '\0' character to an out-of-bounds address.

Sign extension error in the ReadDIBImage function in ImageMagick before 6.3.5-9 allows context-dependent attackers to execute arbitrary code via a crafted width value in an image file, which triggers an integer overflow and a heap-based buffer overflow.
