USN-5908-1: Sudo vulnerability

Releases

• Ubuntu 22.10
• Ubuntu 22.04 LTS

Packages

• sudo - Provide limited super user privileges to specific users

Details

It was discovered that Sudo incorrectly handled the per-command chroot
feature. In certain environments where Sudo is configured with a rule that
contains a CHROOT setting, a local attacker could use this issue to cause
Sudo to crash, resulting in a denial of service, or possibly escalate
privileges.

Update instructions

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

Ubuntu 22.10

• sudo-ldap - 1.9.11p3-1ubuntu1.2
• sudo - 1.9.11p3-1ubuntu1.2

Ubuntu 22.04

• sudo-ldap - 1.9.9-1ubuntu2.3
• sudo - 1.9.9-1ubuntu2.3

In general, a standard system update will make all the necessary changes.
