Ubuntu Security Notice USN-6738-1
April 22, 2024<\/p>\n
lxd vulnerability
==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 18.04 LTS (Available with Ubuntu Pro)
– Ubuntu 16.04 LTS (Available with Ubuntu Pro)<\/p>\n
Summary:<\/p>\n
LXD could be made to bypass integrity checks if it received specially crafted
input.<\/p>\n
Software Description:
– lxd: Container hypervisor based on LXC<\/p>\n
Details:<\/p>\n
Fabian B\u00e4umer, Marcus Brinkmann, and J\u00f6rg Schwenk discovered that LXD
incorrectly handled the handshake phase and the use of sequence numbers in SSH
Binary Packet Protocol (BPP). If a user or an automated system were tricked
into opening a specially crafted input file, a remote attacker could possibly
use this issue to bypass integrity checks.<\/p>\n
Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
package versions:<\/p>\n
Ubuntu 18.04 LTS (Available with Ubuntu Pro):
lxd 3.0.3-0ubuntu1~18.04.2+esm1
lxd-client 3.0.3-0ubuntu1~18.04.2+esm1
lxd-tools 3.0.3-0ubuntu1~18.04.2+esm1<\/p>\n
Ubuntu 16.04 LTS (Available with Ubuntu Pro):
