CVE-2018-10779 LibTIFF vulnerabilities
Title: LibTIFF vulnerabilities
Summary: LibTIFF could be made to crash or run programs as your login if it opened a
specially crafted file.
It was discovered that LibTIFF incorrectly handled certain malformed
images. If a user or automated system were tricked into opening a specially
crafted image, a remote attacker could crash the application, leading to a
denial of service, or possibly execute arbitrary code with user privileges.
Instructions: In general, a standard system update will make all the necessary changes.

libtiff: integer overflow in libtiff/tif_dirwrite.c resulting in an invalid pointer dereference
An Invalid Address dereference was discovered in TIFFWriteDirectoryTagTransferfunction in libtiff/tif_dirwrite.c in LibTIFF 4.0.10, affecting the cpSeparateBufToContigBuf function in tiffcp.c. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted tiff file. This is different from CVE-2018-12900.
Statement: This report appears to be a duplicate of CVE-2018-17000. While the crash manifests differently, both vulnerabilities are fixed by the same upstream commit.
