hw/net/xgmac.c in the XGMAC Ethernet controller in QEMU before 07-20-2020 has a buffer overflow. This occurs during packet transmission and affects the highbank and midway emulated machines. A guest user or process could use this flaw to crash the QEMU process on the host resulting in a denial of service or potential privileged code execution. This was fixed in commit 5519724a13664b43e225ca05351c60b4468e4555.

 | The vulnerability of the xgmac_enet_send function in the hw/net/xgmac.c file of the QEMU hardware emulation software arises from a lack of mechanism for checking the size of copied data. This allows a malicious actor to gain access to protected information, compromise its integrity, and cause service failures. | 23 Dec 202000:00 | – | bdu_fstec |
