CVE-2026-106464

computes the certificate signature's length as without first checking that is non-zero.

Published Oct 14, 2026 · updated Oct 15, 2026

computes the certificate signature's length as without first checking that is non-zero. A certificate whose signature is an empty ASN.1 BIT STRING therefore parses successfully and leaves the certificate holding a signature length of and a signature pointer one byte past the end of the buffer. Certificates are parsed from the peer during the TLS handshake, so the input is remote and unauthenticated.
