Synopsis: Low: libguestfs security, bug fix, and enhancement update
Issue Date: 2012-06-20
CVE Numbers: CVE-2012-2690
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. (CVE-2012-2690)
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.
