encrypt user directories after a system upgrade to Lion. Since the
patch only limits further exposure, though, we recommend that all
users on the system change their passwords if user folders were
encrypted using the legacy version of FileVault prior to and after an
upgrade to OS X 10.7."

Updated libarchive packages that fix two security issues are now
available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

The libarchive programming library can create and read several
different streaming archive formats, including GNU tar and cpio. It
can also read ISO 9660 CD-ROM images.

Two heap-based buffer overflow flaws were discovered in libarchive. If
a user were tricked into expanding a specially crafted ISO 9660 CD-ROM
image or tar archive with an application using libarchive, it could
cause the application to crash or, potentially, execute arbitrary code
with the privileges of the user running the application.
(CVE-2011-1777, CVE-2011-1778)

All libarchive users should upgrade to these updated packages, which
contain backported patches to correct these issues. All running
applications using libarchive must be restarted for this update to
take effect."

"Updated libarchive packages that fix two security issues are now
available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

The libarchive programming library can create and read several
different streaming archive formats, including GNU tar and cpio. It
can also read ISO 9660 CD-ROM images.

Two heap-based buffer overflow flaws were discovered in libarchive. If
a user were tricked into expanding a specially crafted ISO 9660 CD-ROM
image or tar archive with an application using libarchive, it could
cause the application to crash or, potentially, execute arbitrary code
with the privileges of the user running the application.
(CVE-2011-1777, CVE-2011-1778)

All libarchive users should upgrade to these updated packages, which
contain backported patches to correct these issues. All running
applications using libarchive must be restarted for this update to
take effect."
