"This update for tiff fixes the following issues :

  - CVE-2017-9935: There was a heap-based buffer overflow in
    the t2p_write_pdf function in tools/tiff2pdf.c. This
    heap overflow could lead to different damages. For
    example, a crafted TIFF document can lead to an
    out-of-bounds read in TIFFCleanup, an invalid free in
    TIFFClose or t2p_free, memory corruption in
    t2p_readwrite_pdf_image, or a double free in t2p_free.
    Given these possibilities, it probably could cause
    arbitrary code execution (bsc#1046077)

  - CVE-2017-17973: There is a heap-based use-after-free in
    the t2p_writeproc function in tiff2pdf.c. (bsc#1074318)

  - CVE-2018-5784: There is an uncontrolled resource
    consumption in the TIFFSetDirectory function of
    tif_dir.c. Remote attackers could leverage this
    vulnerability to cause a denial of service via a crafted
    tif file. This occurs because the declared number of
    directory entries is not validated against the actual
    number of directory entries (bsc#1081690)

This update was imported from the SUSE:SLE-12:Update update project."
