NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-kvm-tools package and not the qemu-kvm-tools package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2018.03 relevant fixed versions and status.

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.
