Package : libpgjava
Version : 42.2.5-2+deb10u3
CVE ID : CVE-2022-41946

pgjdbc is an open source postgresql JDBC Driver. In affected versions
a prepared statement using either `PreparedStatement.setText(int,
InputStream)` or `PreparedStatemet.setBytea(int, InputStream)` will
create a temporary file if the InputStream is larger than 2k. This
will create a temporary file which is readable by other users on
Unix like systems, but not MacOS. On Unix like systems, the system's
temporary directory is shared between all users on that system. Because
of this, when files and directories are written into this directory
they are, by default, readable by other users on that same system.

For Debian 10 buster, this problem has been fixed in version
42.2.5-2+deb10u3.

We recommend that you upgrade your libpgjava packages.
