CVE-2017-18233 An Integer overflow in the Chunk class in RIFF.cpp allows remote attackers to cause a denial of service (infinite loop) via crafted XMP data in an .avi file. 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.
