EPSS · scored 2026-10-28

libcurl 7.14.0 through 7.16.3, when built with GnuTLS support, does not check SSL/TLS certificate expiration or activation dates, which allows remote attackers to bypass certain access restrictions.

advisories (1)

Vendor and ecosystem advisories describing this.

CURL-CVE-2007-3564GnuTLS insufficient cert verification2007-07-10vendor · osvUS
libcurl (when built to use GnuTLS) fails to verify that a peer's certificate has not already expired or has not yet become valid. This allows malicious servers to present certificates to libcurl that were not rejected properly. Notably, the CA certificate and common name checks are still in place which reduces the risk for random servers to take advantage of this flaw.
