Several security vulnerabilities have been discovered in QEMU, a fast processor emulator. CVE-2021-20257 net: e1000: infinite loop while processing transmit descriptors CVE-2021-20255 A stack overflow via an infinite recursion vulnerability was found in the eepro100 i8255x device emulator of QEMU...

Denial Of Service (DoS)

qemu is vulnerable to denial of service. A use-after-free flaw in the MegaRAID emulator allows an attacker to crash the QEMU process due to an error while processing SCSI I/O requests in the case of an error mptsasfreerequest that does not dequeue the request object req from a pending requests...

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.
