[jira] Updated: (DERBY-5126) ResultSet.getDouble() on a character
or varchar column with some values will hang on JVM's impacted by
CVE-2010-4476 - Java Runtime Environment hangs when converting
"2.2250738585072012e-308" to a binary floating-point number
[ https://issues.apache.org/jira/browse/DERBY-5126?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kathey Marsden updated DERBY-5126:
----------------------------------
Issue Type: Bug (was: Improvement)
Summary: ResultSet.getDouble() on a character or varchar column with some values will hang on JVM's impacted by CVE-2010-4476 - Java Runtime Environment hangs when converting "2.2250738585072012e-308" to a binary floating-point number (was: Add Derby test case for CVE-2010-4476 - Java Runtime Environment hangs when converting "2.2250738585072012e-308" to a binary floating-point number)
I changed the description to better describe the Derby impact. I will close this issue invalid as soon as I add the test.

> There is a known serious JVM issue with both Sun and IBM JVM's that can cause a hang with the following code and perhaps other cases:
> public class ReproCVE20104476 {
> private static final String PROBLEM_NUMBER_STRING="2.2250738585072012e-308" ;
> public static void main(String[] args) throws Exception {
> Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
> Connection conn = DriverManager.getConnection("jdbc:derby:wombat;create=true");
> // clean up from a previous run
> Statement s = conn.createStatement();
> try {
> s.executeUpdate("DROP TABLE T");
> } catch (SQLException se) {
> if (!se.getSQLState().equals("42Y55"))
> throw se;
> }
> s.executeUpdate("CREATE TABLE T (d1 VARCHAR(30))");
> PreparedStatement ps = conn.prepareStatement("INSERT INTO T VALUES (?)");
> ps.setString(1, PROBLEM_NUMBER_STRING);
> ps.executeUpdate();
> ResultSet rs = s.executeQuery("SELECT * from T");
> rs.next();
> double d = rs.getDouble(1);
> System.out.println("double value = " + d);
> }
> }
> The IBM announcement and fix is here:
> http://www.ibm.com/developerworks/java/jdk/alerts/cve-2010-4476.html
> There is a link from that page to the Oracle announcement.
> I am not sure yet if Mac or other JVM's are affected.
> I would like to check a regression test into trunk at some point soon, but this will require that all people running Derby tests upgrade their JVM's, so want to set a reasonable deadline. Does April 15 sound reasonable? Also are there any JVM's/platforms that should be excluded because there is not a fix available yet?
> Thanks
