A flaw was found in the way the Libraries component of OpenJDK handled blacklists of untrusted certificates. Alternate certificate encodings were not considered, causing certain certificate fingerprints to not be blacklisted, possibly leading to untrusted certificates being accepted.

Improper buffer restrictions in network subsystem in provisioned Intel(R) AMT and Intel(R) ISM versions before 11.8.79, 11.12.79, 11.22.79, 12.0.68 and 14.0.39 may allow an unauthenticated user to potentially enable escalation of privilege via network access. On un-provisioned systems, an authenticated user may potentially enable escalation of privilege via local access.

In BIND 9.10.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.10.5-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker that can reach a vulnerable system with a specially crafted query packet can trigger a crash. To be vulnerable, the system must: be running BIND that was built with "--enable-native-pkcs11" be signing one or more zones with an RSA key be able to receive queries from a possible attacker

In BIND 9.0.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker on the network path for a TSIG-signed request, or operating the server receiving the TSIG-signed request, could send a truncated response to that request, triggering an assertion failure, causing the server to exit. Alternately, an off-path attacker would have to correctly guess when a TSIG-signed request was sent, along with other characteristics of the packet and message, and spoof a truncated response to trigger an assertion failure, causing the server to exit.

In BIND 9.14.0 -> 9.16.5, 9.17.0 -> 9.17.3, If a server is configured with both QNAME minimization and 'forward first' then an attacker who can send queries to it may be able to trigger the condition that will cause the server to crash. Servers that 'forward only' are not affected.

In BIND 9.15.6 -> 9.16.5, 9.17.0 -> 9.17.3, An attacker who can establish a TCP connection with the server and send data on that connection can exploit this to trigger the assertion failure, causing the server to exit.

In BIND 9.9.12 -> 9.9.13, 9.10.7 -> 9.10.8, 9.11.3 -> 9.11.21, 9.12.1 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.12-S1 -> 9.9.13-S1, 9.11.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker who has been granted privileges to change a specific subset of the zone's content could abuse these unintended additional privileges to update other contents of the zone.

A flaw was found in the Linux kernel. The generation of the device ID from the network RNG internal state is predictable. The highest threat from this vulnerability is to data confidentiality.

DISPUTED scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows."

An issue was discovered in the Linux kernel 5.5 through 5.7.9, as used in Xen through 4.13.x for x86 PV guests. An attacker may be granted the I/O port permissions of an unrelated task. This occurs because tssinvalidateiobitmap mishandling causes a loss of synchronization between the I/O bitmaps of TSS and Xen, aka CID-cadfad870154.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Oracle Java Runtime Environment. Interaction with the JavaFX library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the rendering of HTML in JavaFX. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process.

An unspecified vulnerability in Oracle Java SE and Java SE Embedded related to the 2D component could allow an unauthenticated attacker to obtain sensitive information resulting in a low confidentiality impact using unknown attack vectors.

A flaw was found in the DerValue class in the Libraries component of OpenJDK. An incorrect implementation of the DerValue.equals() method could cause the class to raise an exception not declared to be thrown by the DerValue.

A flaw was found in the DerInputStream class in the Libraries component of OpenJDK. A DER (Distinguished Encoding Rules) encoded input using indefinite length encoding not supported by the DerInputStream could cause it to raise an exception not declared to be thrown by the DerInputStream.

A flaw was found in the way the ForkJoinPool class in the Libraries component of OpenJDK handled its access control context. This could possibly lead to code being executed with incorrect permissions, possibly leading to bypass of certain intended restrictions defined by a SecurityManager.

A flaw was found in the way the JSSE component of OpenJDK performed TLS server name verification. The HostnameChecker class did not check if names stored in TLS server's X.509 certificate are in the normalized form, possibly leading to an incorrect name being matched.

A flaw was found in the way the XMLSchemaValidator class in the JAXP component of OpenJDK enforced the "use-grammar-pool-only" feature. A specially-crafted XML file could possibly use this flaw to manipulate with the validation process in certain cases.

A flaw was found in the way the imaging library in the 2D component of OpenJDK performed affine transformations of images. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.

An unspecified vulnerability in Java SE related to the Libraries component could allow an unauthenticated attacker to cause low confidentiality impact, low integrity impact, and no availability impact.

OpenSSH is vulnerable to a man-in-the-middle attack, caused by an observable discrepancy flaw. An attacker could exploit this vulnerability to launch a man-in-the-middle attack and gain access to the communication channel between endpoints to obtain sensitive information or further compromise the system.

NTP is vulnerable to a denial of service, caused by a memory leak when a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file in ntpd. By sending specially-crafted packets, a remote authenticated attacker could exploit this vulnerability to consume all available memory resources.

In ISC BIND9 versions BIND 9.11.14 -> 9.11.19, BIND 9.14.9 -> 9.14.12, BIND 9.16.0 -> 9.16.3, BIND Supported Preview Edition 9.11.14-S1 -> 9.11.19-S1: Unless a nameserver is providing authoritative service for one or more zones and at least one zone contains an empty non-terminal entry containing an asterisk ("") character, this defect cannot be encountered. A would-be attacker who is allowed to change zone content could theoretically introduce such a record in order to exploit this condition to cause denial of service, though we consider the use of this vector unlikely because any such attack would require a significant privilege level and be easily traceable.

An attacker who is permitted to send zone data to a server via zone transfer can exploit this to intentionally trigger the assertion failure with a specially constructed zone, denying service to clients.

A vulnerability was found in libpcre in PCRE before 8.44 allows an integer overflow via a large number after a (?C substring.

An issue was discovered in Django 2.2 before 2.2.13 and 3.0 before 3.0.7. Query parameters generated by the Django admin ForeignKeyRawIdWidget were not properly URL encoded, leading to a possibility of an XSS attack.

An issue was discovered in Django 2.2 before 2.2.13 and 3.0 before 3.0.7. In cases where a memcached backend does not perform key validation, passing malformed cache keys could result in a key collision, and potential data leakage.

A flaw was found in the Linux Kernel in versions after 4.5-rc1 in the way mremap handled DAX Huge Pages. This flaw allows a local attacker with access to a DAX enabled storage to escalate their privileges on the system.
