CVE-2019-20812 1 Linux 1 Linux Kernel 2021-06-14 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in the Linux kernel before 5.4.7. The prb_calc_retire_blk_tmo() function in net/packet/af_packet.c can result in a denial of service (CPU consumption and soft lockup) in a certain failure case involving TPACKET_V3, aka CID-b43d1f9f7067.
CVE-2019-19922 1 Linux 1 Linux Kernel 2021-06-14 2.1 LOW 5.5 MEDIUM
kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words, although this slice expiration would typically be seen with benign workloads, it is possible that an attacker could calculate how many stray requests are required to force an entire Kubernetes cluster into a low-performance state caused by slice expiration, and ensure that a DDoS attack sent that number of stray requests. An attack does not affect the stability of the kernel; it only causes mismanagement of application execution.)
CVE-2021-26945 1 Openexr 1 Openexr 2021-06-11 4.3 MEDIUM 5.5 MEDIUM
An integer overflow leading to a heap-buffer overflow was found in OpenEXR in versions before 3.0.1. An attacker could use this flaw to crash an application compiled with OpenEXR.

CVE-2020-10697 1 Redhat 1 Ansible Tower 2021-06-08 3.6 LOW 4.4 MEDIUM
A flaw was found in Ansible Tower when running Openshift. Tower runs a memcached, which is accessed via TCP. An attacker can take advantage of writing a playbook polluting this cache, causing a denial of service attack. This attack would not completely stop the service, but in the worst-case scenario, it can reduce the Tower performance, for which memcached is designed. Theoretically, more sophisticated attacks can be performed by manipulating and crafting the cache, as Tower relies on memcached as a place to pull out setting values. Confidential and sensitive data stored in memcached should not be pulled, as this information is encrypted. This flaw affects Ansible Tower versions before 3.6.4, Ansible Tower versions before 3.5.6 and Ansible Tower versions before 3.4.6.

CVE-2019-15538 6 Canonical, Debian, Fedoraproject and 3 more 28 Ubuntu Linux, Debian Linux, Fedora and 25 more 2021-06-02 7.8 HIGH 7.5 HIGH
An issue was discovered in xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS partially wedges when a chgrp fails on account of being out of disk quota. xfs_setattr_nonsize is failing to unlock the ILOCK after the xfs_qm_vop_chown_reserve call fails. This is primarily a local DoS attack vector, but it might result as well in remote DoS if the XFS filesystem is exported for instance via NFS.
CVE-2021-21419 2 Eventlet, Fedoraproject 2 Eventlet, Fedora 2021-05-27 5.0 MEDIUM 5.3 MEDIUM
Eventlet is a concurrent networking library for Python. A websocket peer may exhaust memory on Eventlet side by sending very large websocket frames. Malicious peer may exhaust memory on Eventlet side by sending highly compressed data frame. A patch in version 0.31.0 restricts websocket frame to reasonable limits. As a workaround, restricting memory usage via OS limits would help against overall machine exhaustion, but there is no workaround to protect Eventlet process.
