-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Low: libguestfs security, bug fix, and enhancement update Advisory ID: RHSA-2012:0774-04 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0774.html Issue date: 2012-06-20 CVE Names: CVE-2012-2690 ===================================================================== 1. Summary: 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - x86_64 Red Hat Enterprise Linux Workstation (v. 6) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - x86_64 3. Description: 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. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 5.
