OpenSSL internal certificate security bypass
|openssl-internal-certificate-sec-bypass (69613)||Medium Risk|
OpenSSL could allow a remote attacker to bypass security restrictions, caused by the improper acceptance of a CRL whose nextUpdate field is in the past by internal certificate verification routines. An attacker could exploit this vulnerability to bypass CRL updates.
Refer to OpenSSL Security Advisory [6 September 2011] for patch, upgrade or suggested workaround information. See References.
