New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

Synopsis

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

Description

This update for qemu fixes the following issues :

Fixed potential privilege escalation in virtfs (CVE-2021-20181 bsc#1182137)

Fixed out-of-bound access in iscsi (CVE-2020-11947 bsc#1180523)

Fixed out-of-bound access in vmxnet3 emulation (CVE-2021-20203 bsc#1181639)

Fixed out-of-bound access in ARM interrupt handling (CVE-2021-20221 bsc#1181933)

Fixed vfio-pci device on s390 enters error state (bsc#1179717 bsc#1179719)

Fixed 'Failed to try-restart [email protected]' error while updating the qemu-guest-agent. (bsc#1178565)

Apply fixes to qemu scsi passthrough with respect to timeout and error conditions, including using more correct status codes. Add more qemu tracing which helped track down these issues (bsc#1178049)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
