CVE-2021-20194 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Openshift Container Platform 2024-11-21 7.8 High
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-2021-20185 1 Moodle 1 Moodle 2024-11-21 5.3 Medium
It was found in Moodle before version 3.10.1, 3.9.4, 3.8.7 and 3.5.16 that messaging did not impose a character limit when sending messages, which could result in client-side (browser) denial of service for users receiving very large messages.
CVE-2021-20108 1 Zohocorp 1 Manageengine Assetexplorer 2024-11-21 7.5 High
Manage Engine Asset Explorer Agent 1.0.34 listens on port 9000 for incoming commands over HTTPS from Manage Engine Server. The HTTPS certificates are not verified which allows any arbitrary user on the network to send commands over port 9000. While these commands may not be executed (due to authtoken validation), the Asset Explorer agent will reach out to the manage engine server for an HTTP request. During this process, AEAgent.cpp allocates 0x66 bytes using "malloc". This memory is never free-ed in the program, causing a memory leak. Additionally, the instruction sent to aeagent (ie: NEWSCAN, DELTASCAN, etc) is converted to a unicode string, but is never freed. These memory leaks allow a remote attacker to exploit a Denial of Service scenario through repetitively sending these commands to an agent and eventually crashing it the agent due to an out-of-memory condition.
