Detailsinfo

A vulnerability was found in libvirt up to 5.x (Virtualization Software). It has been classified as problematic. This affects an unknown part of the component API. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

A NULL pointer dereference was found in the libvirt API responsible introduced in upstream version 3.10.0, and fixed in libvirt 6.0.0, for fetching a storage pool based on its target path. In more detail, this flaw affects storage pools created without a target path such as network-based pools like gluster and RBD. Unprivileged users with a read-only connection could abuse this flaw to crash the libvirt daemon, resulting in a potential denial of service.

The weakness was shared 06/02/2020 as Bug 1790725 as not defined bug report (Bugzilla). The advisory is shared at bugzilla.redhat.com. This vulnerability is uniquely identified as CVE-2020-10703 since 03/20/2020. The exploitability is told to be easy. It is possible to initiate the attack remotely. A authentication is necessary for exploitation. Neither technical details nor an exploit are publicly available.
