Prior to 1.8.3, function identity.extractIssuerURL splits (via a call to strings.Split) its argument (which is untrusted data) on periods. As a result, in the face of a malicious request with an (invalid) OIDC identity token in the payload containing many period characters, a call to extractIssuerURL incurs allocations to the tune of O(n) bytes (where n stands for the length of the function&#39;s argument), with a constant factor of about 16. This vulnerability is fixed in 1.8.3.</p> <p><strong>Affected:</strong> sigstore fulcio</p> <p>Fulcio is a free-to-use certificate authority for issuing code signing certificates for an OpenID Connect (OIDC) identity.
