Qemu: qcow1: validate image size to avoid out-of-bounds memory access
Published Nov 4, 2014
4.6
MEDIUMCVSS 2.0
EPSS 0.60%
Description
Integer overflow in the qcow_open function in block/qcow.c in QEMU before 1.7.2 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a large image size, which triggers a buffer overflow or out-of-bounds read.
