Security Fix(es): * glib: integer overflow in g_bytes_new function on 64-bit platforms due to an implicit cast from 64 bits to 32 bits (CVE-2021-27219) * kernel: userspace applications can misuse the KVM API to cause a write of 16 bytes at an offset up to 32 GB from vcpu->run (CVE-2021-3501) * polkit: local privilege escalation using polkit_system_bus_name_get_creds_sync() (CVE-2021-3560) * hw: vt-d related privilege escalation (CVE-2020-24489) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Bug Fix(es): * Previously, systemtap dependencies were not included in the RHV-H channel. Therefore, systemtap could not be installed. In this release, the systemtap dependencies have been included in the channel, resolving the issue. (BZ#1903997) 4.
