Description Eugene Teo (Security Response) 2011-05-09 02:50:53 UTC

Structures "l2cap_conninfo" and "rfcomm_conninfo" have one padding
byte each. This byte in "cinfo" is copied to userspace uninitialized.

Acknowledgements:

Red Hat would like to thank Marek Kroemeke and Filip Palian for reporting this issue.
