Description
The socket implementation in net/core/sock.c in the Linux kernel before 2.6.34 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service (memory consumption) by sending a large amount of network traffic, as demonstrated by netperf UDP tests.
Affected configurations
• linux linux kernel (< 2.6.34)
• vmware esx 4.0
• vmware esx 4.1
• redhat enterprise linux 4.0
