Overview

Affected versions of this package are vulnerable to Out-of-Bounds. The X509_cmp_time function in crypto/x509/x509_vfy.c allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted length field in ASN1_TIME data, as demonstrated by an attack against a server that supports client authentication with a custom verification callback.
