Red Hat Product Errata RHSA-2012:0774 0 normal SHIPPED_LIVE Low: libguestfs security, bug fix, and enhancement update 2012-06-19 19:29:50 UTC

Description Jan Lieskovsky 2012-06-12 08:52:58 UTC 
A security flaw was found in the way virt-edit tool of libguestfs, a library for accessing and modifying guest disk images, performed file editing in a virtual machine (new file was created, when original file was used leading to loss of attributes likes file permissions, file owner or SELinux context for the edited file). If certain sensitive files were edited using virt-edit, they would become world-readable.
