OESA-2021-1128 qemu security update

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. QEMU has two operating modes: Full system emulation. In this mode, QEMU emulates a full system for example a PC, including one or several processors and various peripherals. It can be used to launch...

A use-after-free flaw was found in the MegaRAID emulator of QEMU. This issue occurs while processing SCSI I/O requests in the case of an error mptsas_free_request() that does not dequeue the request object 'req' from a pending requests queue. This flaw allows a privileged guest user to crash the QEMU process on the host resulting in a denial of service. Versions between 2.10.0 and 5.2.0 are potentially affected.

CVE-2021-3392

CVE-2021-3392 is a use-after-free vulnerability in the QEMU MegaRAID emulator. It occurs when processing SCSI I/O requests during an error path in mptsas_free_request() where the request object may not be dequeued from the pending queue, allowing a privileged guest to crash the host QEMU process ...

Stack overflow

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...

QEMU: slirp: use-after-free in ip_reass() function in ip_input.c

A use-after-free flaw was found in the SLiRP networking implementation of the QEMU emulator. Specifically, this flaw occurs in the ipreass routine while reassembling incoming IP fragments whose combined size is bigger than 65k. This flaw allows an attacker to crash the QEMU process on the host,...
