Descriptions

An issue was discovered in Exempi through 2.4.4. XMPFiles/source/FileHandlers/TIFF_Handler.cpp mishandles a case of a zero length, leading to a heap-based buffer over-read in the MD5Update() function in third-party/zuid/interfaces/MD5.cpp.

Se ha descubierto un problema en Exempi hasta su versión 2.4.4. XMPFiles/source/FileHandlers/TIFF_Handler.cpp gestiona de manera incorrecta un caso de longitud cero que conduce a una sobrelectura de búfer basada en memoria dinámica (heap) en la función MD5Update() en third-party/zuid/interfaces/MD5.cpp.

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.
