A flaw was found in the libvirt libxl driver. A malicious guest could continuously reboot itself and cause libvirtd on the host to deadlock or crash, resulting in a denial of service condition.
An information exposure flaw in openstack-tripleo-heat-templates allows an external user to discover the internal IP or hostname. An attacker could exploit this by checking the www_authenticate_uri parameter (which is visible to all end users) in configuration files. This would give sensitive information which may aid in additional system exploitation. This flaw affects openstack-tripleo-heat-templates versions prior to 11.6.1.
An authorization flaw was found in Foreman Ansible. An authenticated attacker with certain permissions to create and run Ansible jobs can access hosts through job templates. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the descriptor's address belongs to the non direct access region, due to num_buffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting in a denial of service condition, or potentially execute code on the host with the privileges of the QEMU process.
A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat.
An issue was discovered in Grafana through 7.3.4, when integrated with Zabbix. The Zabbix password can be found in the api_jsonrpc.php HTML source code. When the user logs in and allows the user to register, one can right click to view the source code and use Ctrl-F to search for password in api_jsonrpc.php to discover the Zabbix account password and URL address.
A use-after-free flaw was found in the Linux kernel’s FUSE filesystem in the way a user triggers write(). This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation.
The golang.org/x/crypto/ssh package before 0.0.0-20220314234659-1baeb1ce4c0b for Go allows an attacker to crash a server in certain circumstances involving AddHostKey.
