CVE-2017-18233 Exempi vulnerabilities
Title: Exempi vulnerabilities
Summary: Exempi could be made to crash or run programs if it opened a specially
crafted file.
It was discovered that Exempi incorrectly handled certain media files. If a
user or automated system were tricked into opening a specially crafted
file, a remote attacker could cause Exempi to hang or crash, resulting in a
denial of service, or possibly execute arbitrary code.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2018-7728 exempi: Heap-based buffer overflow in third-party/zuid/interfaces/MD5.cpp:MD5Update() allows for denial of service via crafted TIFF image
Exempi through version 2.4.4 is vulnerable to a heap-based buffer overflow in third-party/zuid/interfaces/MD5.cpp:MD5Update() caused by a mishandled case of zero length in XMPFiles/source/FileHandlers/TIFF_Handler.cpp. An attacker could exploit this to cause a denial of service via crafted TIFF image file.
