Description

An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU before version 4.6.0. The flaw exists in the bootp_input() function and could occur while processing a UDP packet that is smaller than the size of the 'bootp_t' structure. A malicious guest could use this flaw to leak 10 bytes of uninitialized heap memory from the host.
