CVE-2021-20194

CVE-2021-20194

There is a vulnerability in the linux kernel versions higher than 5.2 (if kernel compiled with config params CONFIG_BPF_SYSCALL=y , CONFIG_BPF=y , CONFIG_CGROUPS=y , CONFIG_CGROUP_BPF=y , CONFIG_HARDENED_USERCOPY not set, and BPF hook to getsockopt is registered). As result of BPF execution, the local user can trigger bug in __cgroup_bpf_run_filter_getsockopt() function that can lead to heap overflow (because of non-hardened usercopy). The impact of attack could be deny of service or possibly privileges escalation.

CVE-2021-20252

CVE-2021-20252

A flaw was found in Red Hat 3scale API Management Platform 2. The 3scale backend does not perform preventive handling on user-requested date ranges in certain queries allowing a malicious authenticated user to submit a request with a sufficiently large date range to eventually yield an internal server error resulting in denial of service. The highest threat from this vulnerability is to system availability.

CVE-2021-21323

CVE-2021-21323

Brave is an open source web browser with a focus on privacy and security. In Brave versions 1.17.73-1.20.103, the CNAME adblocking feature added in Brave 1.17.73 accidentally initiated DNS requests that bypassed the Brave Tor proxy. Users with adblocking enabled would leak DNS requests from Tor windows to their DNS provider. (DNS requests that were not initiated by CNAME adblocking would go through Tor as expected.) This is fixed in Brave version 1.20.108

CVE-2021-20182

CVE-2021-20182

A privilege escalation flaw was found in openshift4/ose-docker-builder. The build container runs with high privileges using a chrooted environment instead of runc. If an attacker can gain access to this build container, they can potentially utilize the raw devices of the underlying node, such as the network and storage devices, to at least escalate their privileges to that of the cluster admin. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

CVE-2021-26680

CVE-2021-26680

A remote authenticated command injection vulnerability was discovered in Aruba ClearPass Policy Manager version(s): Prior to 6.9.5, 6.8.8-HF1, 6.7.14-HF1. A vulnerability in the ClearPass web-based management interface allows remote authenticated users to run arbitrary commands on the underlying host. A successful exploit could allow an attacker to execute arbitrary commands as root on the underlying operating system leading to complete system compromise.
