CVE-2020-35506 |
A use-after-free vulnerability was found in the am53c974 SCSI host bus adapter emulation of QEMU in versions before 6.0.0 during the handling of the 'Information Transfer' command (CMD_TI). This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service or potential code execution with the privileges of the QEMU process.

CVE-2020-10701 |
A missing authorization flaw was found in the libvirt API responsible for changing the QEMU agent response timeout. This flaw allows read-only connections to adjust the time that libvirt waits for the QEMU guest agent to respond to agent commands. Depending on the timeout value that is set, this flaw can make guest agent commands fail because the agent cannot respond in time. Unprivileged users with a read-only connection could abuse this flaw to set the response timeout for all guest agent messages to zero, potentially leading to a denial of service. This flaw affects libvirt versions before 6.2.0. Published: May 27, 2021; 3:15:07 PM -0400 |

CVE-2020-10697 |
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. Published: May 27, 2021; 3:15:07 PM -0400 |

CVE-2021-28652 |
An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to incorrect parser validation, it allows a Denial of Service attack against the Cache Manager API. This allows a trusted client to trigger memory leaks that. over time, lead to a Denial of Service via an unspecified short query string. This attack is limited to clients with Cache Manager API access privilege. Published: May 27, 2021; 8:15:08 AM -0400 |

CVE-2021-28651 |
An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a buffer-management bug, it allows a denial of service. When resolving a request with the urn: scheme, the parser leaks a small amount of memory. However, there is an unspecified attack methodology that can easily trigger a large amount of memory consumption. Published: May 27, 2021; 8:15:08 AM -0400 |

CVE-2021-3527 |
A flaw was found in the USB redirector device (usb-redir) of QEMU. Small USB packets are combined into a single, large transfer request, to reduce the overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array (VLA) on the stack without proper validation. Since the total size is not bounded, a malicious guest could use this flaw to influence the array length and cause the QEMU process to perform an excessive allocation on the stack, resulting in a denial of service.
