When deserializing untrusted or corrupted data, it is possible for a reader to consume memory beyond the allowed constraints and thus lead to out of memory on the system.

This issue affects Java applications using Apache Avro Java SDK up to and including 1.11.2.  Users should update to apache-avro version 1.11.3 which addresses this issue.

Apache Avro Java SDK: Arbitrary Code Execution when reading Avro Data (Java SDK)
Schema parsing in the Java SDK of Apache Avro 1.11.3 and previous versions allows bad actors to execute arbitrary code.
Users are recommended to upgrade to version 1.11.4 or 1.12.0, which fix this issue.

SSRF vulnerability using the Aegis DataBinding in Apache CXF
A SSRF vulnerability using the Aegis DataBinding in versions of Apache CXF before 4.0.4, 3.6.3 and 3.5.8 allows an attacker to perform SSRF style attacks on webservices that take at least one parameter of any type. Users of other data bindings (including the default databinding) are not impacted.

Apache Log4j 1.x (EOL) allows Denial of Service (DoS)
** UNSUPPORTED WHEN ASSIGNED ** When using the Chainsaw or SocketAppender components with Log4j 1.x on JRE less than 1.7, an attacker that manages to cause a logging entry involving a specially-crafted (ie deeply nested) hashmap or hashtable (depending on which logging component is in use) to be processed could exhaust the available memory in the virtual machine and achieve Denial of Service when the object is deserialized. This issue affects Apache Log4j before 2. Affected users are recommended to update to Log4j 2.x. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

HyperSQL DataBase vulnerable to remote code execution when processing untrusted input
Those using `java.sql.Statement` or `java.sql.PreparedStatement` in hsqldb (HyperSQL DataBase) to process untrusted input may be vulnerable to a remote code execution attack. By default it is allowed to call any static method of any Java class in the classpath resulting in code execution. The issue can be prevented by updating to 2.7.1 or by setting the system property "hsqldb.method_class_names" to classes which are allowed to be called. For example, `System.setProperty("hsqldb.method_class_names", "abc")` or Java argument `-Dhsqldb.method_class_names="abc"` can be used. From version 2.7.1 all classes by default are not accessible except those in `java.lang.Math` and need to be manually enabled.

HTTP Request Smuggling in Netty
Netty 4.1.43.Final allows HTTP Request Smuggling because it mishandles Transfer-Encoding whitespace (such as a [space]Transfer-Encoding:chunked line) and a later Content-Length header. This issue exists because of an incomplete fix for CVE-2019-16869.

Apache Xalan Java XSLT library integer truncation issue when processing malicious XSLT stylesheets
The Apache Xalan Java XSLT library is vulnerable to an integer truncation issue when processing malicious XSLT stylesheets. This can be used to corrupt Java class files generated by the internal XSLTC compiler and execute arbitrary Java bytecode.

A fix for this issue was published in September 2022 as part of an anticipated 2.7.3 release.
