The png_handle_cHRM function in pngrutil.c in libpng 1.5.4, when color-correction support is enabled, allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a malformed PNG image containing a cHRM chunk associated with a certain zero value.

According to its banner, the remote Apple TV 2nd generation or later device has a version of iOS that is prior to 5.1. It is, therefore, reportedly affected by several vulnerabilities :

  - An uninitialized memory access issue in the handling of     Sorenson encoded movie files could lead to arbitrary     code execution. (CVE-2012-3722)

  - Following the DNAv4 protocol, the device may broadcast     MAC addresses of previously accessed networks when     connecting to a Wi-Fi network. (CVE-2012-3725)

  - A buffer overflow in libtiff's handling of ThunderScan     encoded TIFF images could lead to arbitrary code     execution. (CVE-2011-1167)

  - Multiple memory corruption issues in libpng's handling     of PNG images could lead to arbitrary code execution.
    (CVE-2011-3026 / CVE-2011-3048 / CVE-2011-3328)

  - A double free issue in ImageIO's handling of JPEG     images could lead to arbitrary code execution.
    (CVE-2012-3726)

  - An integer overflow issue in libTIFF's handling of TIFF     images could lead to arbitrary code execution.
    (CVE-2012-1173)

  - A stack-based buffer overflow in the handling of ICU     locale IDs could lead to arbitrary code execution.
    (CVE-2011-4599)

  - Multiple vulnerabilities in libxml could have a variety     of impacts, including arbitrary code execution.
    (CVE-2011-1944 / CVE-2011-2821 / CVE-2011-2834 /     CVE-2011-3919)
