NVD Description

Note: Versions mentioned in the description apply only to the upstream container-tools:rhel8/fuse-overlayfs package and not the container-tools:rhel8/fuse-overlayfs package as distributed by RHEL. See How to fix? for RHEL:8 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.
