Synopsis
The remote Amazon Linux AMI host is missing a security update.
Description
tcp_emu in slirp/tcp_subr.c (aka slirp/src/tcp_subr.c) in QEMU 3.0.0 uses uninitialized data in an snprintf call, leading to Information disclosure. (CVE-2019-9824)
tcp_emu in tcp_subr.c in libslirp 4.1.0, as used in QEMU 4.2.0, mismanages memory, as demonstrated by IRC DCC commands in EMU_IRC.
This can cause a heap-based buffer overflow or other out-of-bounds access which can lead to a DoS or potential execute arbitrary code.
(CVE-2020-7039)
In libslirp 4.1.0, as used in QEMU 4.2.0, tcp_subr.c misuses snprintf return values, leading to a buffer overflow in later code.
(CVE-2020-8608)
Solution
Run 'yum update qemu-kvm' to update your system.
