"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)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
