Descriptions

An issue was discovered in Exempi before 2.4.4. Integer overflow in the Chunk class in XMPFiles/source/FormatSupport/RIFF.cpp allows remote attackers to cause a denial of service (infinite loop) via crafted XMP data in a .avi file.

Se ha descubierto un problema en versiones anteriores a la 2.4.4 de Exempi. Desbordamiento de enteros en la clase Chunk en XMPFiles/source/FormatSupport/RIFF.cpp permite que los atacantes remotos provoquen una denegación de servicio (bucle infinito) mediante datos XMP manipulados en un archivo .avi.

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.
