Ubuntu Security Notice USN-5745-1
November 28, 2022

shadow vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

– Ubuntu 22.10
– Ubuntu 22.04 LTS
– Ubuntu 20.04 LTS
– Ubuntu 18.04 LTS
– Ubuntu 16.04 ESM
– Ubuntu 14.04 ESM


shadow could be made to overwrite files.

Software Description:
– shadow: system login tools


Florian Weimer discovered that shadow was not properly copying and removing
user directory trees, which could lead to a race condition. A local attacker
could possibly use this issue to setup a symlink attack and alter or remove
directories without authorization.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.10:
libsubid4 1:4.11.1+dfsg1-2ubuntu1.1

passwd 1:4.11.1+dfsg1-2ubuntu1.1
uidmap 1:4.11.1+dfsg1-2ubuntu1.1

Ubuntu 22.04 LTS:
