The remote host is missing an update to libtiff
announced via advisory MDVSA-2010:146.
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.
Affected: 2010.0, 2010.1
Solution:
To upgrade automatically use MandrakeUpdate or urpmi. The verification
of md5 checksums and GPG signatures is performed automatically for you.
