CVE-2020-1730 6 Canonical, Fedoraproject, Libssh and 3 more 6 Ubuntu Linux, Fedora, Libssh and 3 more 2026-06-17 5.0 MEDIUM 5.3 MEDIUM
A flaw was found in libssh versions before 0.8.9 and before 0.9.4 in the way it handled AES-CTR (or DES ciphers if enabled) ciphers. The server or client could crash when the connection hasn't been fully initialized and the system tries to cleanup the ciphers when closing the connection. The biggest threat from this vulnerability is system availability.
CVE-2020-1700 4 Canonical, Ceph, Opensuse and 1 more 4 Ubuntu Linux, Ceph, Leap and 1 more 2026-06-17 6.8 MEDIUM 6.5 MEDIUM
A flaw was found in the way the Ceph RGW Beast front-end handles unexpected disconnects. An authenticated attacker can abuse this flaw by making multiple disconnect attempts resulting in a permanent leak of a socket connection by radosgw. This flaw could lead to a denial of service condition by pile up of CLOSE_WAIT sockets, eventually leading to the exhaustion of available resources, preventing legitimate users from connecting to the system.
CVE-2020-1472 8 Canonical, Debian, Fedoraproject and 5 more 15 Ubuntu Linux, Debian Linux, Fedora and 12 more 2026-06-17 9.3 HIGH 5.5 MEDIUM
An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC). An attacker who successfully exploited the vulnerability could run a specially crafted application on a device on the network. To exploit the vulnerability, an unauthenticated attacker would be required to use MS-NRPC to connect to a domain controller to obtain domain administrator access. Microsoft is addressing the vulnerability in a phased two-part rollout. These updates address the vulnerability by modifying how Netlogon handles the usage of Netlogon secure channels. For guidelines on how to manage the changes required for this vulnerability and more information on the phased rollout, see How to manage the changes in Netlogon secure channel connections associated with CVE-2020-1472 (updated September 28, 2020). When the second phase of Windows updates become available in Q1 2021, customers will be notified via a revision to this security vulnerability. If you wish to be notified when these updates are released, we recommend that you register for the security notifications mailer to be alerted of content changes to this advisory.

CVE-2020-17538 3 Artifex, Canonical, Debian 3 Ghostscript, Ubuntu Linux, Debian Linux 2026-06-17 4.3 MEDIUM 5.5 MEDIUM
A buffer overflow vulnerability in GetNumSameData() in contrib/lips4/gdevlips.c of Artifex Software GhostScript from v9.18 to v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.
CVE-2020-17489 4 Canonical, Debian, Gnome and 1 more 4 Ubuntu Linux, Debian Linux, Gnome-shell and 1 more 2026-06-17 1.9 LOW 4.3 MEDIUM
An issue was discovered in certain configurations of GNOME gnome-shell through 3.36.4. When logging out of an account, the password box from the login dialog reappears with the password still visible. If the user had decided to have the password shown in cleartext at login time, it is then visible for a brief moment upon a logout. (If the password were never shown in cleartext, only the password length is revealed.)
