Package        : libpgjava
CVE ID         : CVE-2020-13692 CVE-2022-21724 CVE-2022-26520
Debian Bug     : 962828

Several security vulnerabilities have been found in libpgjava, the official
PostgreSQL JDBC Driver.

CVE-2020-13692

    An XML External Entity (XXE) weakness was found in PostgreSQL JDBC.

CVE-2022-21724

    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.

CVE-2022-26520

    An attacker (who controls the jdbc URL or properties) can call
    java.util.logging.FileHandler to write to arbitrary files through the
    loggerFile and loggerLevel connection properties.

For the oldstable distribution (buster), these problems have been fixed
in version 42.2.5-2+deb10u1.

For the stable distribution (bullseye), these problems have been fixed in
version 42.2.15-1+deb11u1.

We recommend that you upgrade your libpgjava packages.
