Details

The X509cmptime function in crypto/x509/x509vfy.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted length field in ASN1TIME data, as demonstrated by an attack against a server that supports client authentication with a custom verification callback.
