Various issues were discovered in exempi, a library to parse XMP metadata that may cause a denial of service or may have other unspecified impact via crafted files.

CVE-2017-18234 An issue was discovered that allows remote attackers to cause a denial of service (invalid memcpy with resultant use-after-free) or possibly have unspecified other impact via a .pdf file containing JPEG data.

CVE-2017-18236 The ASF_Support::ReadHeaderObject function in ASF_Support.cpp allows remote attackers to cause a denial of service (infinite loop) via a crafted .asf file.
