A flaw was found in libnbd. The client did not always correctly verify the NBD server's certificate when using TLS to connect to an NBD server. This issue allows a man-in-the-middle attack on NBD traffic.

A flaw was found in the GTK library. Under certain conditions, it is possible for a library to be injected into a GTK application from the current working directory.

A flaw was found in OpenJPEG. A resource exhaustion can occur in the opj_t1_decode_cblks function in tcd.c through a crafted image file, causing a denial of service.

A flaw was found in OpenJPEG. Maliciously constructed pictures can cause the program to enter a large loop and continuously print warning messages on the terminal.

A flaw was found in NetworkManager. When a system running NetworkManager with DEBUG logs enabled and an interface eth1 configured with LLDP enabled, a malicious user could inject a malformed LLDP packet. NetworkManager would crash, leading to a denial of service.

A vulnerability was found in OpenJPEG similar to CVE-2019-6988. This flaw allows an attacker to bypass existing protections and cause an application crash through a maliciously crafted file.

A race condition vulnerability was discovered in how signals are handled by OpenSSH's server (sshd). If a remote attacker does not authenticate within a set time period, then sshd's SIGALRM handler is called asynchronously. However, this signal handler calls various functions that are not async-signal-safe, for example, syslog(). As a consequence of a successful attack, in the worst case scenario, an attacker may be able to perform a remote code execution (RCE) as an unprivileged user running the sshd server.

A flaw was found in the cockpit package. This flaw allows an authenticated user to kill any process when enabling the pam_env's user_readenv option, which leads to a denial of service (DoS) attack.

A flaw was found in the QEMU disk image utility (qemu-img) 'info' command. A specially crafted image file containing a `json:{}` value describing block devices in QMP could cause the qemu-img process on the host to consume large amounts of memory or CPU time, leading to denial of service or read/write to an existing external file.

A denial of service vulnerability was found in the 389-ds-base LDAP server. This issue may allow an authenticated user to cause a server denial of service while attempting to log in with a user with a malformed hash in their password.
