3. Description:
The redhat-virtualization-host packages provide the Red Hat Virtualization
Host.
These packages include redhat-release-virtualization-host. Red Hat
Virtualization Hosts (RHVH) are installed using a special build of Red Hat
Enterprise Linux with only the packages required to host virtual machines.
RHVH features a Cockpit user interface for monitoring the host's resources
and performing administrative tasks.
Security Fix(es):
* kernel: Use After Free in unix_gc() which could result in a local
privilege escalation (CVE-2021-0920)
* kernel: use-after-free in RDMA listen() (CVE-2021-4028)
* kernel: fget: check that the fd still exists after getting a ref to it
(CVE-2021-4083)
* kernel: xfs: raw block device data leak in XFS_IOC_ALLOCSP IOCTL
(CVE-2021-4155)
* aide: heap-based buffer overflow on outputs larger than B64_BUF
(CVE-2021-45417)
* kernel: possible privileges escalation due to missing TLB flush
(CVE-2022-0330)
* openssl: Infinite loop in BN_mod_sqrt() reachable when parsing
certificates (CVE-2022-0778)
* kernel: failing usercopy allows for use-after-free exploitation
(CVE-2022-22942)
* cyrus-sasl: failure to properly escape SQL input allows an attacker to
execute arbitrary SQL commands (CVE-2022-24407)
* expat: Malformed 2- and 3-byte UTF-8 sequences can lead to arbitrary code
execution (CVE-2022-25235)
* expat: Namespace-separator characters in "xmlns[:prefix]" attribute
values can lead to arbitrary code execution (CVE-2022-25236)
* expat: Integer overflow in storeRawNames() (CVE-2022-25315)
