Description Tomas Hoger 2014-01-14 12:00:12 UTC

A flaw was found in the way the Networking component of OpenJDK checked permissions of code to listen on network ports.  An untrusted Java application or applet could possibly use this flaw to bypass certain Java sandbox restrictions.

Comment 1 Tomas Hoger 2014-01-14 21:21:50 UTC

Public now via Oracle CPU January 2014.  Fixed in Oracle JDK 7u51, 6u71 and 5.0u61.

  Change in Default Socket Permissions

  The default socket permissions assigned to all code including untrusted code
  have been changed in this release. Previously, all code was able to bind any
  socket type to any port number greater than or equal to 1024. It is still
  possible to bind sockets to the ephemeral port range on each system. The
  exact range of ephemeral ports varies from one operating system to another,
  but it is typically in the high range (such as from 49152 to 65535). The new
  restriction is that binding sockets outside of the ephemeral range now
  requires an explicit permission in the system security policy.

  Most applications using client tcp sockets and a security manager will not
  see any problem, as these typically bind to ephemeral ports anyway.
  Applications using datagram sockets or server tcp sockets (and a security
  manager) may encounter security exceptions where none were seen before. If
  this occurs, users should review whether the port number being requested is
  expected, and if this is the case, a socket permission grant can be added
  to the local security policy, to resolve the issue.

  See 8011786 (not public).

Ephemeral port range for Linux is 32768-65535.
