Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been found in libvirt, allowing remote |
| 19 |
attackers to execute arbitrary code or cause Denial of Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
libvirt is a C toolkit for manipulating virtual machines. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 app-emulation/libvirt < 1.0.5.1-r3 >= 1.0.5.1-r3 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
An error in the virNetMessageFree() function in |
| 38 |
rpc/virnetserverclient.c can lead to a use-after-free. Additionally, a |
| 39 |
socket leak in the remoteDispatchStoragePoolListAllVolumes command can |
| 40 |
lead to file descriptor exhaustion. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A remote attacker could cause certain errors during an RPC connection |
| 46 |
to cause a message to be freed without being removed from the message |
| 47 |
queue, possibly resulting in execution of arbitrary code or a Denial of |
| 48 |
Service condition. Additionally, a remote attacker could repeatedly |
| 49 |
issue the command to list all pool volumes, causing a Denial of Service |
| 50 |
condition. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All libvirt users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot -v ">=app-emulation/libvirt-1.0.5.1-r3" |
| 64 |
|
| 65 |
