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.
Metrics
NVD enrichment efforts reference publicly available information to associate
vector strings. CVSS information contributed by other sources is also
displayed.
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.
