Vulnerability  : insecure communication protocol
Problem type   : local
Debian-specific: no
CVE Id         : CVE-2010-2526
Debian Bug     : 591204


Alasdair Kergon discovered that the cluster logical volume manager daemon
(clvmd) in lvm2, The Linux Logical Volume Manager, does not verify client
credentials upon a socket connection, which allows local users to cause a
denial of service.

For the stable distribution (lenny), this problem has been fixed in
version 2.02.39-8

For the testing distribution (squeeze), and the unstable distribution (sid),
this problem has been fixed in version 2.02.66-3


We recommend that you upgrade your lvm2 package.
