SUSE SLED15 / SLES15 Security Update : qemu (SUSE-SU-2022:3795-1)

high Nessus Plugin ID 166690

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3795-1 advisory.

 - A use-after-free vulnerability was found in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU. The flaw occurs while processing repeated messages to cancel the current SCSI request via the lsi_do_msgout function. This flaw allows a malicious privileged user within the guest to crash the QEMU process on the host, resulting in a denial of service. (CVE-2022-0216)

 - ** DISPUTED ** softmmu/physmem.c in QEMU through 7.0.0 can perform an uninitialized read on the translate_fail path, leading to an io_readx or io_writex crash. NOTE: a third party states that the Non- virtualization Use Case in the qemu.org reference applies here, i.e., Bugs affecting the non- virtualization use case are not considered security bugs at this time. (CVE-2022-35414)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
