"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."
