A flaw was found in the Serialization component of OpenJDK. A reference to an uninitialized class descriptor encountered during object stream deserialization could cause an unexpected exception to be raised when processing an untrusted serialized input.

A flaw was found in the Nashorn JavaScript engine in the Scripting component of OpenJDK. The state machine of the regular expression Parser did not correctly handle empty string nodes in certain cases, which could cause an unexpected exception to be raised when processing a specially crafted regular expression.

A flaw was found in the Nashorn JavaScript engine in the Scripting component of OpenJDK. Processing of the forward references prior to checking for regular expression syntax errors could cause an unexpected exception to be raised when processing a specially crafted regular expression.

A flaw was found in the Serialization component of OpenJDK. The invokeWriteObject() method of the ObjectStreamClass method failed to catch InstantiationError exception during object stream deserialization, which could cause an unexpected exception to be raised when processing an untrusted serialized input.

A flaw was found in the Security component of OpenJDK. It was discovered that the unmarshalKeyInfo() method of the DOMKeyInfoFactory class and the unmarshalXMLSignature() method of the DOMXMLSignatureFactory class could raise exceptions not declared as thrown by these methods when reading key info or XML signature data from XML input.

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

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.

An input validation flaw was found in the URL class implementation in the Networking component of OpenJDK. A URL class instance could have been created for a URL string containing invalid characters not permitted in URLs.

It was discovered that crypto provider implementations in the JCE component of OpenJDK for crypto algorithms such as AES or SHA did not perform array bounds checks. This could lead to out-of-bounds access if compiler intrinsics were used instead of the Java runtime implementations of the specific operations.

It was discovered that the implementation of the Throwable class in the Utilities component of OpenJDK did not sufficiently validate serial stream before deserializing suppressed exceptions. A specially-crafted input could cause a Java application to construct inconsistent object and possibly use an excessive amount of system resources when deserialized.

It was discovered that the implementation of the Collections class in the Utilities component of OpenJDK did not limit the amount of memory allocated when creating object instance from a serialized form. A specially-crafted input could cause a Java application to use an excessive amount of memory when deserialized.

A deserialization flaw was discovered in Apache Tomcat's use of a FileStore. An attacker can exploit the flaw if all of the following are true: An attacker is able to control the contents and name of a file on the server. The server is configured to use the PersistenceManager with a FileStore. The PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker-provided object to be deserialized. The attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over. If all these conditions are true, the attacker can use a specifically crafted request to trigger Remote Code Execution through deserialization of the file under their control.

This flaw affects the following Tomcat versions: 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54, and 7.0.0 to 7.0.103.

A flaw was found in Apache Tomcat, where the payload length in a WebSocket frame was not correctly validated. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service. The highest threat from this vulnerability is to system availability.

Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding; and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.

ePO doesn't allow a regular privileged user to delete tasks or assignments. Insecure direct object references that allow a least privileged user to manipulate the client task and client task assignments, hence escalating his/her privilege.

ASN.1 strings are represented internally within OpenSSL as an ASN1STRING structure which contains a buffer holding the string data and a field holding the buffer length. This contrasts with normal C strings which are repesented as a buffer for the string data which is terminated with a NUL (0) byte. Although not a strict requirement, ASN.1 strings that are parsed using OpenSSL's own "d2i" functions (and other similar parsing functions) as well as any string whose value has been set with the ASN1STRINGset() function will additionally NUL terminate the byte array in the ASN1STRING structure. However, it is possible for applications to directly construct valid ASN1STRING structures which do not NUL terminate the byte array by directly setting the "data" and "length" fields in the ASN1STRING array. This can also happen by using the ASN1STRINGset0() function. Numerous OpenSSL functions that print ASN.1 data have been found to assume that the ASN1STRING byte array will be NUL terminated, even though this is not guaranteed for strings that have been directly constructed. Where an application requests an ASN.1 structure to be printed, and where that ASN.1 structure contains ASN1STRINGs that have been directly constructed by the application without NUL terminating the "data" field, then a read buffer overrun can occur. The same thing can also occur during name constraints processing of certificates (for example if a certificate has been directly constructed by the application instead of loading it via the OpenSSL parsing functions, and the certificate contains non NUL terminated ASN1STRING structures). It can also occur in the X509get1email(), X509REQget1email() and X509get1ocsp() functions. If a malicious actor can cause an application to directly construct an ASN1STRING and then process it through one of the affected OpenSSL functions then this issue could be hit. This might result in a crash (causing a Denial of Service attack). It could also result in the disclosure of private memory contents (such as private keys, or sensitive plaintext). Fixed in OpenSSL 1.1.1j (Affected 1.1.1-1.1.1k). Fixed in OpenSSL 1.0.2za (Affected 1.0.2-1.0.2y).

A flaw was discovered in the way the Libraries component of OpenJDK processed X.509 certificates. Values of Object Identifiers (OIDs) were "interned", possibly allowing a malicious X.509 certificate to trigger excessive memory usage in a Java application processing such certificate.

A flaw was found in the Serialization component of OpenJDK handled serialization filter. A process-wide filter could have been modified by setting jdk.serialFilter system property at runtime, possibly leading to a bypass of the intended filter during deserialization.

A flaw was found in the URL class implementation in the Networking component of OpenJDK. An incorrect check to determine if a URLStreamHandler is builtin or not can lead to incorrect URL normalization in certain cases.

A flaw was found in the way the GssKrb5Base class in the Security component of OpenJDK validated properties of SASL messages included in Kerberos GSSAPI, omitting required token checks. An remote attacker with ability to manipulate network traffic between server and client using Kerberos GSSAPI could possibly perform message modification that would not be detected during message decoding.

A flaw was found in the what the BeanContextSupport class in the Serialization component of OpenJDK handled exceptions during deserialization. A specially-crafted input could cause a Java application to use an excessive amount of resources when deserialized.
