"This update for tiff fixes the following issues :

Security issue fixed :

CVE-2018-10779: TIFFWriteScanline in tif_write.c had a heap-based
buffer over-read, as demonstrated by bmp2tiff.(bsc#1092480)

CVE-2018-17100: 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.
(bsc#1108637)

CVE-2018-17101: 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. (bsc#1108627)

CVE-2018-17795: The function t2p_write_pdf in tiff2pdf.c allowed
remote attackers to cause a denial of service (heap-based buffer
overflow and application crash) or possibly have unspecified other
impact via a crafted TIFF file, a similar issue to CVE-2017-9935.
(bsc#1110358)

CVE-2018-16335: newoffsets handling in ChopUpSingleUncompressedStrip
in tif_dirread.c allowed remote attackers to cause a denial of service
(heap-based buffer overflow and application crash) or possibly have
unspecified other impact via a crafted TIFF file, as demonstrated by
tiff2pdf. This is a different vulnerability than CVE-2018-15209.
(bsc#1106853)
