DEBIAN-CVE-2021-3416

A potential stack overflow via infinite loop issue was found in various NIC emulators of QEMU in versions up to and including 5.2.0. The issue occurs in loopback mode of a NIC wherein reentrant DMA checks get bypassed. A guest user/process may use this flaw to consume CPU cycles or crash the QEMU...

Denial Of Service (DoS)

QEMU is vulnerable to denial of service. A heap-based buffer overflow flaw was discovered in the way QEMU's AMD PC-Net II Ethernet Controller emulation received certain packets in loopback mode. A privileged user with the CAPSYSRAWIO capability inside a guest could use this flaw to crash the host...

Qemu: net: pcnet: heap overflow vulnerability in pcnet_receive

A heap-based buffer overflow flaw was discovered in the way QEMU's AMD PC-Net II Ethernet Controller emulation received certain packets in loopback mode. A privileged user with the CAPSYSRAWIO capability inside a guest could use this flaw to crash the host QEMU process resulting in denial of...

Qemu: net: pcnet: buffer overflow in non-loopback mode

A buffer overflow flaw was found in the way QEMU's AMD PC-Net II emulation validated certain received packets from a remote host in non-loopback mode. A remote, unprivileged attacker could potentially use this flaw to execute arbitrary code on the host with the privileges of the QEMU process. Not...

QEMU AMD PC-Net II Ethernet Controller Packet Length Buffer Overflow Vulnerability

QEMU is a simulation processor software developed by French programmer Fabrice Bellard. The software is fast and cross-platform. A buffer overflow vulnerability exists in the 'pcnetreceive' function in the hw/net/pcnet.c file in QEMU version 2.5.0, which originates from the program failing to...
