|Bugzilla:||652534: CVE-2010-4161 kernel: rhel5 commit 6865201191 caused deadlock|
The MITRE CVE dictionary describes this issue as:
The udp_queue_rcv_skb function in net/ipv4/udp.c in a certain Red Hat build of the Linux kernel 2.6.18 in Red Hat Enterprise Linux (RHEL) 5 allows attackers to cause a denial of service (deadlock and system hang) by sending UDP traffic to a socket that has a crafted socket filter, a related issue to CVE-2010-4158.
This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 4 as it did not backport the upstream commit 93821778 that introduced this. It did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG as they have backported the upstream commit fda9ef5d that addressed this. Future kernel update in Red Hat Enterprise Linux 5 may address this flaw.
