NVD Description

Note: Versions mentioned in the description apply only to the upstream slirp4netns-debuginfo package and not the slirp4netns-debuginfo package as distributed by Rocky-Linux. See How to fix? for Rocky-Linux: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.
