A vulnerability has been found in Apptainer which could result in the usage of an unexpected of a container.
|Package||app-containers/apptainer on all architectures|
|Affected versions||< 1.1.2|
|Unaffected versions||>= 1.1.2|
Apptainer is the container system for secure high-performance computing.
The Go module "sif" version 2.8.0 and older, which is a statically linked dependency of Apptainer, does not verify that the hash algorithm(s) used are cryptographically secure when verifying digital signatures.
An image whose verification relies on a cryptographically insecure hash algorithm could be replaced, resulting in users using an image other than the one that was expected.
There is no known workaround at this time.
All Apptainer users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-containers/apptainer-1.1.2"
