Overview

Affected versions of this package are vulnerable to Denial Of Service (Dos). The do_free_upto function in crypto/cms/cms_smime.c allows remote attackers to cause a denial of service (infinite loop) via vectors that trigger a NULL value of a BIO data structure, as demonstrated by an unrecognized X.660 OID for a hash function.
