CVE-2009-1417: gnutls-cli in GnuTLS before 2.6.6 does not verify the activation and expiration times of X.509 certificates...

gnutls-cli in GnuTLS before 2.6.6 does not verify the activation and expiration times of X.509 certificates, which allows remote attackers to successfully present a certificate that is (1) not yet valid or (2) no longer valid, related to lack of time checks in the _gnutls_x509_verify_certificate function in lib/x509/verify.c in libgnutls_x509, as used by (a) Exim, (b) OpenLDAP, and (c) libsoup.

Security readout for executives and security teams

GnuTLS before 2.6.6 could accept TLS certificates even when their valid date range had not started or had already expired. This weakens certificate-based trust and could let a remote party present an invalid certificate successfully in affected GnuTLS-dependent clients or services. Exposure is most likely in legacy systems running GnuTLS before 2.6.6, especially where certificate validation depends on affected GnuTLS code paths in gnutls-cli, Exim, OpenLDAP, or libsoup. Treat this as a legacy exposure cleanup item. It is not flagged as known exploited in the supplied data, but affected systems may make invalid certificates appear trustworthy, which undermines TLS assurance. Mitigation focus: Upgrade GnuTLS to version 2.6.6 or later where supported.; Check operating-system vendor advisories for backported GnuTLS fixes.; Inventory Exim, OpenLDAP, libsoup, and gnutls-cli deployments using GnuTLS..
