 Some or all NICs supported by r8169 seem to ignore the buffer sizes in
 RX descriptors, and will write up to the global maximum frame size.
 This means a remote attacker can overflow RX buffers, probably
 allowing for code injection.  This should be fixed by the patch posted

This is CVE-2009-1389.

The severity of this issue is still debated.
