CVE-2022-28327
No exploitation reported by the sources we read.
- Published2022-04-20
Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
The generic P-256 feature in crypto/elliptic in Go before 1.17.9 and 1.18.x before 1.18.1 allows a panic via long scalar input.
