TITLE

QEMU Integer overflow vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-013856

DESCRIPTION

The Bluetooth subsystem in QEMU mishandles negative values for length variables, leading to memory corruption. QEMU Contains an integer overflow vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. QEMU is prone to an integer-overflow vulnerability because it fails to adequately bounds-check user-supplied data before copying it to an insufficiently sized memory buffer. Attackers can exploit this issue to crash the QEMU instance, resulting in a denial-of-service condition. Due to the nature of this issue, code execution may be possible but this has not been confirmed
