| Package | Affected versions | Patched versions |
|---|---|---|
| libslirp | = 4.1.0 | |
| qemu | = 4.2.0 |
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.
