A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption). This vulnerability is similar with the older CVE-2019-18808.

Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1.

Apache HttpClient versions prior to version 4.5.13 and 5.0.3 can misinterpret malformed authority component in request URIs passed to the library as java.net.URI object and pick the wrong target host for request execution.

Cross Site scripting vulnerability on Micro Focus Enterprise Server and Enterprise developer, affecting all versions prior to version 5.0 Patch Update 8. The vulnerability could allow an attacker to trigger administrative actions when an administrator viewed malicious data left by the attacker (stored XSS) or followed a malicious link (reflected XSS).

Insufficiently protected credentials vulnerability on Micro Focus enterprise developer and enterprise server, affecting all version prior to 4.0 Patch Update 16, and version 5.0 Patch Update 6. The vulnerability could allow an attacker to transmit hashed credentials for the user account running the Micro Focus Directory Server (MFDS) to an arbitrary site, compromising that account's security.

Go before 1.12.11 and 1.3.x before 1.13.2 can panic upon an attempt to process network traffic containing an invalid DSA public key. There are several attack scenarios, such as traffic from a client to a server that verifies client certificates.

Reflected XSS on Micro Focus Enterprise Developer and Enterprise Server, all versions prior to version 3.0 Patch Update 20, version 4.0 Patch Update 12, and version 5.0 Patch Update 2. The vulnerability could be exploited to redirect a user to a malicious page or forge certain types of web requests.

Go before 1.12.10 and 1.13.x before 1.13.1 allow HTTP Request Smuggling.

Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.

A flaw was found in the Linux kernel's NFS implementation, all versions 3.x and all versions 4.x up to 4.20. An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer dereference by using an invalid NFS sequence. This can panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will be lost.
