Solution
Please Install the Updated Packages.
Insight
Multiple vulnerabilities has been discovered and corrected in libtiff: The TIFFYCbCrtoRGB function in LibTIFF 3.9.0 and 3.9.2, as used in ImageMagick, does not properly handle invalid ReferenceBlackWhite values, which allows remote attackers to cause a denial of service (application crash) via a crafted TIFF image that triggers an array index error, related to downsampled OJPEG input. (CVE-2010-2595) Multiple integer overflows in the Fax3SetupState function in tif_fax3.c in the FAX3 decoder in LibTIFF before 3.9.3 allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted TIFF file that triggers a heap-based buffer overflow (CVE-2010-1411). Integer overflow in the TIFFroundup macro in LibTIFF before 3.9.3 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted TIFF file that triggers a buffer overflow (CVE-2010-2065). The TIFFRGBAImageGet function in LibTIFF 3.9.0 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a TIFF file with an invalid combination of SamplesPerPixel and Photometric values (CVE-2010-2483). The TIFFVStripSize function in tif_strip.c in LibTIFF 3.9.0 and 3.9.2 makes incorrect calls to the TIFFGetField function, which allows remote attackers to cause a denial of service (application crash) via a crafted TIFF image, related to downsampled OJPEG input and possibly related to a compiler optimization that triggers a divide-by-zero error (CVE-2010-2597). The TIFFExtractData macro in LibTIFF before 3.9.4 does not properly handle unknown tag types in TIFF directory entries, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted TIFF file (CVE-2010-248). Packages for 2008.0 and 2009.0 are provided as of the Extended Maintenance Program.
