-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2010:146 http://www.mandriva.com/security/ _______________________________________________________________________ Package : libtiff Date : August 6, 2010 Affected: 2010.0, 2010.1 _______________________________________________________________________ Problem Description: 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). Stack-based buffer overflow in the TIFFFetchSubjectDistance function in tif_dirread.c in LibTIFF before 3.9.4 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long EXIF SubjectDistance field in a TIFF file (CVE-2010-2067). tif_getimage.c in LibTIFF 3.9.0 and 3.9.2 on 64-bit platforms, as used in ImageMagick, does not properly perform vertical flips, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted TIFF image, related to downsampled OJPEG input. (CVE-2010-2233). LibTIFF 3.9.4 and earlier does not properly handle an invalid td_stripbytecount field, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted TIFF file, a different vulnerability than CVE-2010-2443 (CVE-2010-2482). The updated packages have been patched to correct these issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-2595 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-1411 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-2065 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-2483 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-2597 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-2481 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-2067 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-2233 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-2482 _______________________________________________________________________ Updated Packages: Mandriva Linux 2010.0: ceb7febb41b948977f6196b5bf31d538 2010.0/i586/libtiff3-3.9.1-4.1mdv2010.0.i586.rpm d38ee02dca1666e8d8f7c628e9debcbe 2010.0/i586/libtiff-devel-3.9.1-4.1mdv2010.0.i586.rpm e022bf3d3badddd3c480b4143a8cc2ec 2010.0/i586/libtiff-progs-3.9.1-4.1mdv2010.0.i586.rpm 6f18f9ce3d9582ea3f6f9ddd7b1680d8 2010.0/i586/libtiff-static-devel-3.9.1-4.1mdv2010.0.i586.rpm 69aa854e6935c2d111e44e84225f6f69 2010.0/SRPMS/libtiff-3.9.1-4.1mdv2010.0.src.rpm Mandriva Linux 2010.0/X86_64: 3965284cc51603cfdc0d9420104b8fd3 2010.0/x86_64/lib64tiff3-3.9.1-4.1mdv2010.0.x86_64.rpm 2768094532f4d1941ef66bae6da6ea15 2010.0/x86_64/lib64tiff-devel-3.9.1-4.1mdv2010.0.x86_64.rpm 2e08c6517abcf34dab75040fbee15212 2010.0/x86_64/lib64tiff-static-devel-3.9.1-4.1mdv2010.0.x86_64.rpm 3c81e78d3c389abcc370add6af857d12 2010.0/x86_64/libtiff-progs-3.9.1-4.1mdv2010.0.x86_64.rpm 69aa854e6935c2d111e44e84225f6f69 2010.0/SRPMS/libtiff-3.9.1-4.1mdv2010.0.src.rpm Mandriva Linux 2010.1: 0ddf3e069a91387a7d85ad5aacd1dd81 2010.1/i586/libtiff3-3.9.2-2.1mdv2010.1.i586.rpm 53d5d64cb3bb34a78d52776d42e0ed16 2010.1/i586/libtiff-devel-3.9.2-2.1mdv2010.1.i586.rpm e549b78e6658cb9a408454bf698e2ead 2010.1/i586/libtiff-progs-3.9.2-2.1mdv2010.1.i586.rpm 821179322f86ba6dcc96dd6afc48fd0f 2010.1/i586/libtiff-static-devel-3.9.2-2.1mdv2010.1.i586.rpm 31563b8124d1953b9c8849e0a63f5422 2010.1/SRPMS/libtiff-3.9.2-2.1mdv2010.1.src.rpm Mandriva Linux 2010.1/X86_64: e858e4c72c5191395d4db7f994ffd7c4 2010.1/x86_64/lib64tiff3-3.9.2-2.1mdv2010.1.x86_64.rpm 6bdce5697bc818f57cb56d22ce989b30 2010.1/x86_64/lib64tiff-devel-3.9.2-2.1mdv2010.1.x86_64.rpm daaf9562d71e8076e87578f25b8dbebe 2010.1/x86_64/lib64tiff-static-devel-3.9.2-2.1mdv2010.1.x86_64.rpm 36d9eef4dd2739944f05fe7edd4e76f8 2010.1/x86_64/libtiff-progs-3.9.2-2.1mdv2010.1.x86_64.rpm 31563b8124d1953b9c8849e0a63f5422 2010.1/SRPMS/libtiff-3.9.2-2.1mdv2010.1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
