Oracle Linux 6 : libguestfs (ELSA-2012-0774)
Low Nessus Plugin ID 68548
SynopsisThe remote Oracle Linux host is missing one or more security updates.
DescriptionFrom Red Hat Security Advisory 2012:0774 :
Updated libguestfs packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
libguestfs is a library for accessing and modifying guest disk images.
It was found that editing files with virt-edit left said files in a world-readable state (and did not preserve the file owner or Security-Enhanced Linux context). If an administrator on the host used virt-edit to edit a file inside a guest, the file would be left with world-readable permissions. This could lead to unprivileged guest users accessing files they would otherwise be unable to.
These updated libguestfs packages include numerous bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.3 Technical Notes for information on the most significant of these changes.
Users of libguestfs are advised to upgrade to these updated packages, which fix these issues and add these enhancements.
SolutionUpdate the affected libguestfs packages.
