Package : libpgjava
Version : 9.4.1212-1+deb9u1
CVE ID : CVE-2022-21724

It was found that libpgjava, the official PostgreSQL JDBC Driver, would be
vulnerable if an attacker controlled jdbc url or properties. The JDBC driver
did not verify if certain classes implemented the expected interface before
instantiating the class. This can lead to code execution loaded via arbitrary
classes.

For Debian 9 stretch, this problem has been fixed in version
9.4.1212-1+deb9u1.

We recommend that you upgrade your libpgjava packages.
