in the Netscape Security Services (NSS) library's implementation of
SSLv2. From their advisory :

The NSS library contains a flaw in SSLv2 record parsing that may lead
to remote compromise. When parsing the first record in an SSLv2
negotiation, the client hello message, the server fails to validate
the length of a record field. As a result, it is possible for an
attacker to trigger a heap-based overflow of arbitrary length.

Note that the vulnerable NSS library is also present in Mozilla-based
browsers. However, it is not believed that browsers are affected, as
the vulnerability is present only in code used by SSLv2 *servers*."
