Mei Wang discovered a multiple integer overflows in LibTIFF which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted TIFF image, which triggers an out-of-bounds write. (CVE-2016-3945)
It was discovered that LibTIFF is vulnerable to a heap buffer overflow in the resulting in DoS or code execution via a crafted BitsPerSample value. (CVE-2017-5225)
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.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected libtiff-tools and / or libtiff4 packages.
