Subject [jira] [Comment Edited] (DERBY-6619) After silently swallowing SecurityExceptions, Derby can leak class loaders
Date Mon, 18 Aug 2014 22:13:21 GMT

----------------------------------------------------------------

Uploading a patch [^derby-6619.diff] which prints warnings on derby.log.

For example, with this invocation:
{code}
java -jar jars/sane/derbyrun.jar server start
{code}
which uses the default security manager, the derby.log looks as in [^derby.log].

> As part of the fix for DERBY-3745, Derby silently swallows security exceptions and leaks
class loaders. This can give rise to denial-of-service attacks. At a minimum, Derby should
report the swallowed exceptions so that the security policy can be corrected and the application
can be hardened against this attack. The swallowing occurs at these locations:
> {noformat}
> org.apache.derby.impl.services.timer.SingletonTimerFactory run Catch java.lang.SecurityException
0 line 175
> org.apache.derby.impl.services.timer.SingletonTimerFactory run Catch java.lang.SecurityException
1 line 158
> {noformat}
