Chapter 1. RHSA-2022:5555-09 Moderate: RHV Manager (ovirt-engine) [ovirt-4.5.1] security, bug fix and update The bugs in this chapter are addressed by advisory RHSA-2022:5555-09. Further information about this advisory is available at https://errata.devel.redhat.com/advisory/96099 1.1. ovirt-engine BZ# 2099650 A bug that caused the upgrade process to fail if the vdc_options table contained records with a NULL default value has been fixed. BZ# 2006625 Previously, memory allocated by hugepages was included in the host memory usage calculation, resulting in high memory usage in the Administration Portal, even with no running VMs, and false VDS_HIGH_MEM_USE warnings in the logs. In this release, hugepages are not included in the memory usage. VDS_HIGH_MEM_USE warnings are logged only when normal (not hugepages) memory usage is above a defined threshold. Memory usage in the Administration Portal is calculated from the normal and hugepages used memory, not from allocated memory. BZ# 2072626 The ovirt-engine-notifier correctly increments the SNMP EngineBoots value after restarts, which enables the ovirt-engine-notifier to work with the SNMPv3 authPriv security level. BZ# 1663217 The hostname and/or FQDN of the VM or VDSM host can change after a virtual machine (VM) is created. Previously, this change could prevent the VM from fetching errata from Red Hat Satellite/Foreman. With this enhancement, errata can be fetched even if the VM hostname or FQDN changes. BZ# 1994144 The email address for notifications is updated correctly on the ``Manage Events'' screen. BZ# 2001923 Previously, when a failed VM snapshot was removed from the Manager database while the volume remained on the storage, subsequent operations failed because there was a discrepancy between the storage and the database. Now, the VM snapshot is retained if the volume is not removed from the storage. BZ# 1782077 An ``isolated threads'' CPU pinning policy has been added. This policy pins a physical core exclusively to a virtual CPU, enabling a complete physical core to be used as the virtual core of a single virtual machine. BZ# 1958032 Previously, live storage migration could fail if the destination volume filled up before it was extended. In the current release, the initial size of the destination volume is larger and the extension is no longer required. BZ# 1976607 VGA has replaced QXL as the default video device for virtual machines. You can switch from QXL to VGA using the API by removing the graphic and video devices from the VM (creating a headless VM) and then adding a VNC graphic device. BZ# 2001574 Previously, when closing the ``Move/Copy disk'' dialog in the Administration Portal, some of the acquired resources were not released, causing browser slowness and high memory usage in environments with many disks. In this release, the memory leak has been fixed. BZ# 2030293 A VM no longer remains in a permanent locked state if the Manager is rebooted while exporting the VM as OVA. BZ# 2068270 Previously, when downloading snapshots, the disk_id was not set, which caused resumption of the transfer operation to fail because locking requires the disk_id to be set. In this release, the disk_id is always set so that the transfer operation recovers after restart. BZ# 2081241 Previously, VMs with one or more VFIO devices, Q35 chipset, and maximum number of vCPUs >= 256 might fail to start because of a memory allocation error reported by the QEMU guest agent. This error has been fixed. BZ# 2105296 Virtual machines with VNC created by earlier Manager versions sometimes failed to migrate to newer hosts because the VNC password was too long. This issue has been fixed. BZ# 1703153 There is a workaround for creating a RHV Manager hostname that is longer than 95 characters. Create a short FQDN, up to 63 characters, for the engine-setup tool. Create a custom certificate and put the short FQDN and a long FQDN (final hostname) into the certificate's Subject Alternate Name field. Configure the Manager to use the custom certificate. Create an /etc/ovirt-engine/engine.conf.d/99-alternate-engine-fqdns.conf file with the following content: SSO_ALTERNATE_ENGINE_FQDNS=``long FQDN'' Restart the ovirt-engine service. If you cannot access the Manager and are using a very long FQDN: 1. Check for the following error message in /var/log/httpd/error_log : ajp_msg_check_header() incoming message is too big NNNN, max is MMMM 2. Add the following line to /etc/httpd/conf.d/z-ovirt-engine-proxy.conf : ProxyIOBufferSize PPPP where PPPP is greater than NNNN in the error message. Restart Apache. 1.2. ovirt-log-collector BZ# 2093795 Rebase package(s) to version: 4.4.6 This fixes an issue which prevented the collection of PostgreSQL data and the documentation of the -log-size option. 1.3. rhv-log-collector-analyzer BZ# 2081559 The rhv-log-collector-analyzer discrepancy tool now detects preallocated QCOW2 images that have been reduced. 1.4. rhvm-branding-rhv BZ# 2092885 The Welcome page of the Administration Portal now displays both the upstream and downstream version names. 1.5. vdsm BZ# 2070045 The host no longer enters a non-responsive state if the OVF store update operation times out because of network errors. 1.6. vulnerability BZ# 1966615 A flaw was found in nodejs-trim-newlines. Node.js has an issue related to regular expression denial-of-service (ReDoS) for the .end() method. BZ# 1981895 A flaw was found in apache-commons-compress. When reading a specially crafted 7Z archive, the construction of the list of codecs that decompress an entry can result in an infinite loop. This flaw allows the mounting of a denial of service attack against services that use Compress' SevenZ package. The highest threat from this vulnerability is to system availability. BZ# 1981900 A flaw was found in apache-commons-compress. When reading a specially crafted 7Z archive, Compress can allocate large amounts of memory that leads to an out-of-memory error for very small inputs. This flaw allows the mounting of a denial of service attack against services that use Compress' SevenZ package. The highest threat from this vulnerability is to system availability. BZ# 1981903 A flaw was found in apache-commons-compress. When reading a specially crafted TAR archive, Compress can allocate large amounts of memory that leads to an out-of-memory error for small inputs. This flaw allows the mounting of a denial of service attack against services that use Compress' TAR package. The highest threat from this vulnerability is to system availability. BZ# 1981909 A flaw was found in apache-commons-compress. When reading a specially crafted ZIP archive, Compress can allocate large amounts of memory that leads to an out-of-memory error for small inputs. This flaw allows the mounting of a denial of service attack against services that use Compress' zip package. The highest threat from this vulnerability is to system availability. BZ# 2007557 A regular expression denial of service (ReDoS) vulnerability was found in nodejs-ansi-regex. This could possibly cause an application using ansi-regex to use an excessive amount of CPU time when matching crafted ANSI escape codes. BZ# 2069414 A flaw was found in the Spring Framework. This flaw allows an attacker to craft a special Spring Expression, causing a denial of service. BZ# 2097414 A vulnerability was found in semantic-release. Secrets that are normally masked are accidentally disclosed if they contain characters excluded from uri encoding by encodeURI() . The vulnerability is further limited to execution contexts where push access to the related repository is unavailable without modifying the repository URL to inject credentials.
