VUL-1: kernel: does not properly manage a backlog of received packets,
Last modified: 2011-06-08 13:45:27 UTC
There is a security bug in package 'kernel'.
This bug is public.
There is no coordinated release date (CRD) set.
CVE number: CVE-2010-4805
CVE description: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-4805
CVSS v2 Base Score: 6.1 (moderate) (AV:A/AC:L/Au:N/C:N/I:N/A:C)
Resource Management Errors (CWE-399)
remote denial of service
The socket implementation in net/core/sock.c in the Linux kernel before 2.6.35 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service by sending a large amount of network traffic, related to the sk_add_backlog function and the sk_rmem_alloc socket field. NOTE: this vulnerability exists because of an incomplete fix for CVE-YYYY-NNN.

Could this be a duplicate of Bug #655973? The upstream commit c377411f2494a931ff7facdbb3a6839b1266bcf6 got applied to our kernel trees already in the patch series from that bug.
yes, we got it already.
i checked sle11 sp1, it has the patch, same for sle10 sp3 and sp4.
so yes, it is fixed already.
