Summary
qemu security update
Details

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed.

Security Fix(es):

An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the udp6_input() function and could occur while processing a udp packet that is smaller than the size of the 'udphdr' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality.(CVE-2021-3593)

An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the bootpinput() function and could occur while processing a udp packet that is smaller than the size of the 'bootpt' structure. A malicious guest could use this flaw to leak 10 bytes of uninitialized heap memory from the host. The highest threat from this vulnerability is to data confidentiality.(CVE-2021-3592)

An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the tftpinput() function and could occur while processing a udp packet that is smaller than the size of the 'tftpt' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality.(CVE-2021-3595)
