Red Hat Product Errata RHSA-2006:0575 0 normal SHIPPED_LIVE Important: Updated kernel packages available for Red Hat Enterprise Linux 4 Update 4 2006-08-10 04:00:00 UTC

Description Marcel Holtmann 2006-06-30 19:34:17 UTC
When a packet without any chunks is received, the newconntrack variable in
sctp_packet contains an out of bounds value that is used to look up an pointer
from the array of timeouts, which is then dereferenced, resulting in a crash.
