Subject [jira] Updated: (DERBY-4292) creation of FileInputStream in org.apache.derby.impl.tools.ij.Main not wrapped in privilege block which can cause problems running under SecurityManager
Date Wed, 01 Jul 2009 23:02:47 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4292?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kathey Marsden updated DERBY-4292:
----------------------------------

    Attachment: derby4292.zip

The problem occurs when you specify a file to run on the ij command line when running under
security manager.

Attached is a reproduction for this issue.   Unzip derby4292.zip. Change run.sh to point to
your location and run run.sh.


With the Sun JDK 1.6 JDK I get.
Exception in thread "main" java.security.AccessControlException: access denied (java.io.FilePermission
repro.sql read)
        at java.security.AccessControlContext.checkPermission(AccessControlContext.java:323)
        at java.security.AccessController.checkPermission(AccessController.java:546)
        at java.lang.SecurityManager.checkPermission(SecurityManager.java:532)
        at java.lang.SecurityManager.checkRead(SecurityManager.java:871)
        at java.io.FileInputStream.<init>(FileInputStream.java:100)
        at java.io.FileInputStream.<init>(FileInputStream.java:66)
        at org.apache.derby.impl.tools.ij.Main.mainCore(Main.java:117)
        at org.apache.derby.impl.tools.ij.Main.main(Main.java:73)
        at org.apache.derby.tools.ij.main(ij.java:59)

With IBM 1.6 I don't get an error but I think that is due to an IBM jvm bug which I will file
soon.

> org.apache.derby.impl.tools.ij.Main has this code where the call to FileInputStream is
not wrapped in a privilege block:
>                    try {
>                         in1 = new FileInputStream(file);
>                         if (in1 != null) {
>                             in1 = new BufferedInputStream(in1, utilMain.BUFFEREDFILESIZE);
>                             in = langUtil.getNewInput(in1);
>                         }
>                     } catch (FileNotFoundException e) {
>                         if (Boolean.getBoolean("ij.searchClassPath")) {
>                             in = langUtil.getNewInput(util.getResourceAsStream(file));
>                         }
> This can cause issues when running under SecurityManager
