A vulnerability has been found in Apptainer which could result in the |
| 19 |
usage of an unexpected of a container. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Apptainer is the container system for secure high-performance computing. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 app-containers/apptainer < 1.1.2 >= 1.1.2 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
The Go module "sif" version 2.8.0 and older, which is a statically |
| 38 |
linked dependency of Apptainer, does not verify that the hash |
| 39 |
algorithm(s) used are cryptographically secure when verifying digital |
| 40 |
signatures. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
An image whose verification relies on a cryptographically insecure hash |
| 46 |
algorithm could be replaced, resulting in users using an image other |
| 47 |
than the one that was expected. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All Apptainer users should upgrade to the latest version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=app-containers/apptainer-1.1.2" |
| 61 |
