CVE-2009-3726 Detail

Current Description

The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state.

Vendor Statements (disclaimer)

Official Statement fromRed Hat (12/17/2009)

Red Hat is aware of this issue and is tracking it via the following bug: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=CVE-2009-3726. The Linux kernel as shipped with Red Hat Enterprise Linux 3 did not have support for NFSv4, and therefore is not affected by this issue. It was addressed in Red Hat Enterprise Linux 5, and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2009-1670.html and https://rhn.redhat.com/errata/RHSA-2009-1635.html respectively. A future kernel update in Red Hat Enterprise Linux 4 will address this issue.
