CVE-2009-4537 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-4537):
  drivers/net/r8169.c in the r8169 driver in the Linux kernel 2.6.32.3
  and earlier does not properly check the size of an Ethernet frame
  that exceeds the MTU, which allows remote attackers to (1) cause a
  denial of service (temporary network outage) via a packet with a
  crafted size, in conjunction with certain packets containing A
  characters and certain packets containing E characters; or (2) cause
  a denial of service (system crash) via a packet with a crafted size,
  in conjunction with certain packets containing '\0' characters,
  related to the value of the status register and erroneous behavior
  associated with the RxMaxSize register.  NOTE: this vulnerability
  exists because of an incorrect fix for CVE-2009-1389.
