5 src:
6 2:

12 description: |
13 It was found that QEMU Guest Agent (the "qemu-ga" service) created
14 certain files with world-writable permissions when run in daemon mode
15 (the default mode). An unprivileged guest user could use this flaw to
16 consume all free space on the partition containing the qemu-ga log file, or
17 modify the contents of the log. When a UNIX domain socket transport was
18 explicitly configured to be used (not the default), an unprivileged guest
19 user could potentially use this flaw to escalate their privileges in the
20 guest (CVE-2013-2007).
21
22 Note: This update requires manual action. Refer below for details.
23
24 This update does not change the permissions of the existing log file or
25 the UNIX domain socket. For these to be changed, stop the qemu-ga service,
26 and then manually remove all "group" and "other" permissions on the
27 affected files, or remove the files.
28
29 Also note that after installing this update, files created by the
30 guest-file-open QEMU Monitor Protocol (QMP) command will still continue to
31 be created with world-writable permissions for backwards compatibility.
