SynopsisThe remote SUSE host is missing one or more security updates.
DescriptionThis 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.
