Descriptions

An issue was discovered in QPDF before 7.0.0. There is a large heap-based out-of-bounds read in the Pl_Buffer::write function in Pl_Buffer.cc. It is caused by an integer overflow in the PNG filter.

Se ha descubierto un problema en versiones anteriores a la 7.0.0 de QPDF. Hay una gran lectura fuera de límites basada en memoria dinámica (heap) en la función Pl_Buffer::write en Pl_Buffer.cc. Esto lo ha provocado un desbordamiento de enteros en el filtro PNG.

It was discovered that QPDF incorrectly handled certain malformed files. A remote attacker could use this issue to cause QPDF to crash, resulting in a denial of service, or possibly execute arbitrary code.
