Synopsis:

qemu security updateSummary:

An update for qemu is now available for openEuler-24.03-LTS-SP4Description:

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed.

Security Fix(es):

The hardware emulation in the of_dpa_cmd_add_l2_flood of rocker device model in QEMU, as used in 7.0.0 and earlier, allows remote attackers to crash the host qemu and potentially execute code on the host via execute a malformed program in the guest OS. Note: This has been disputed by multiple third parties as not a valid vulnerability due to the rocker device not falling within the virtualization use case.(CVE-2022-36648)Topic:
