- Security database references:
- In the Debian bugtracking system: Bug 962828.
In Mitre's CVE dictionary: CVE-2020-13692, CVE-2022-21724, CVE-2022-26520.
- More information:
Several security vulnerabilities have been found in libpgjava, the official PostgreSQL JDBC Driver.
An XML External Entity (XXE) weakness was found in PostgreSQL JDBC.
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.
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.
