libtiff-4.0.3-32.el7

The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.

Security Fix(es):

* libtiff: buffer overflow in gif2tiff (CVE-2016-3186)

* libtiff: Heap-based buffer overflow in the cpSeparateBufToContigBuf function resulting in a denial of service or possibly code execution (CVE-2018-12900)

* libtiff: Out-of-bounds write in tif_jbig.c (CVE-2018-18557)

* libtiff: NULL pointer dereference in tif_print.c:TIFFPrintDirectory() causes a denial of service (CVE-2018-7456)

* libtiff: heap-based buffer overflow in tif_lzw.c:LZWDecodeCompat() allows for denial of service (CVE-2018-8905)

* libtiff: heap-based buffer over-read in TIFFWriteScanline function in tif_write.c (CVE-2018-10779)

* libtiff: reachable assertion in TIFFWriteDirectorySec function in tif_dirwrite.c (CVE-2018-10963)

* libtiff: Integer overflow in multiply_ms in tools/ppm2tiff.c (CVE-2018-17100)

* libtiff: Two out-of-bounds writes in cpTags in tools/tiff2bw.c and tools/pal2rgb.c (CVE-2018-17101)

* libtiff: tiff2bw tool failed memory allocation leads to crash (CVE-2018-18661)

CVE-2016-3186
Buffer overflow in the readextension function in gif2tiff.c in LibTIFF 4.0.6 allows remote attackers to cause a denial of service (application crash) via a crafted GIF file.
CVE-2018-10779
TIFFWriteScanline in tif_write.c in LibTIFF 3.8.2 has a heap-based buffer over-read, as demonstrated by bmp2tiff.
CVE-2018-10963
The TIFFWriteDirectorySec() function in tif_dirwrite.c in LibTIFF through 4.0.9 allows remote attackers to cause a denial of service (assertion failure and application crash) via a crafted file, a different vulnerability than CVE-2017-13726.
CVE-2018-12900
Heap-based buffer overflow in the cpSeparateBufToContigBuf function in tiffcp.c in LibTIFF 4.0.9 allows remote attackers to cause a denial of service (crash) or possibly have unspecified other impact via a crafted TIFF file.
CVE-2018-17100
An issue was discovered in LibTIFF 4.0.9. There is a int32 overflow in multiply_ms in tools/ppm2tiff.c, which can cause a denial of service (crash) or possibly have unspecified other impact via a crafted image file.
CVE-2018-17101
An issue was discovered in LibTIFF 4.0.9. There are two out-of-bounds writes in cpTags in tools/tiff2bw.c and tools/pal2rgb.c, which can cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image file.
CVE-2018-18557
LibTIFF 4.0.9 (with JBIG enabled) decodes arbitrarily-sized JBIG into a buffer, ignoring the buffer size, which leads to a tif_jbig.c JBIGDecode out-of-bounds write.
CVE-2018-18661
An issue was discovered in LibTIFF 4.0.9. There is a NULL pointer dereference in the function LZWDecode in the file tif_lzw.c.
CVE-2018-7456
A NULL Pointer Dereference occurs in the function TIFFPrintDirectory in tif_print.c in LibTIFF 4.0.9 when using the tiffinfo tool to print crafted TIFF information, a different vulnerability than CVE-2017-18013. (This affects an earlier part of the TIFFPrintDirectory function that was not addressed by the CVE-2017-18013 patch.)
CVE-2018-8905
In LibTIFF 4.0.9, a heap-based buffer overflow occurs in the function LZWDecodeCompat in tif_lzw.c via a crafted TIFF file, as demonstrated by tiff2ps.
