Synopsis: 2.6.38-15.61 can now be patched using Ksplice
CVEs: CVE-2012-2313 CVE-2012-2319 CVE-2012-2375
Systems running Ubuntu 11.04 Natty can now use Ksplice to patch
against the latest Ubuntu kernel update, 2.6.38-15.61.
INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack on Ubuntu 11.04 Natty
install these updates.
On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.
Alternatively, you can install these updates by running:
# /usr/sbin/uptrack-upgrade -y
DESCRIPTION
* CVE-2012-2313: Privilege escalation in the dl2k NIC.
The D-LINK dl2k network card was missing permission checks in the ioctl
handling function. This would allow an unprivileged user to reconfigure
the low-level link device and trigger a denial-of-service.
* CVE-2012-2319: Buffer overflow mounting corrupted hfs filesystem.
A buffer overflow flaw was found in the hfsplus_bnode_read() function in
the HFS+ file system implementation. This could lead to a denial of
service if a user browsed a specially-crafted HFS+ file system, for
example, by running "ls".
* CVE-2012-2375: Kernel crash in NFSv4.
The upstream fix for CVE-2010-4131 was incomplete and still exploitable
under certain circumstances. nfs4_getfacl decoding causes a kernel
crash when a server returns more than 2 GETATTR bitmap words in response
to the FATTR4_ACL attribute request.
