Description Petr Matousek 2012-01-05 21:30:00 UTC

There isn't proper checking in legacy mode packets such that if two large
packets arrive back to back without the EOP flag set in the first packet, you
can easily overrun your buffer.

Because data is written to the packets after the packet is processed, this
could allow a heap overflow which is exploitable.

Acknowledgements:

Red Hat would like to thank Nicolae Mogoreanu for reporting this issue.
