No affected components available
Impact
The siftool new command and func siftool.New() produce predictable UUID identifiers due to insecure randomness in the version of the github.com/satori/go.uuid module used as a dependency.
Patches
A patch is available in version >= v1.2.3 of the module. Users are encouraged to upgrade.
The patch is commit https://github.com/sylabs/sif/commit/193962882122abf85ff5f5bcc86404933e71c07d
Workarounds
Users passing CreateInfo struct should ensure the ID field is generated using a version of github.com/satori/go.uuid that is not vulnerable to this issue. Unfortunately, the latest tagged release is vulnerable to this issue. One way to obtain a non-vulnerable version is:
go get github.com/satori/go.uuid@75cca531ea763666bc46e531da3b4c3b95f64557
