------------------------------------
> BER indefinite-length octet 0x80 silently decoded as zero length
> ----------------------------------------------------------------
>
> Key: DIRAPI-469
> URL: https://issues.apache.org/jira/browse/DIRAPI-469
> Project: Directory Client API
> Issue Type: Bug
> Affects Versions: 2.1.8
> Reporter: Emmanuel Lécharny
> Priority: Major
> Fix For: 2.1.9
>
>
> An attacker who can inject a *PDU* inspected by a conforming *BER* parser
> (*LDAP*-aware firewall/audit tap) and then decoded by this codec encodes a
> security-relevant element (a control, an extended-op value) with indefinite
> length.
> The inspection layer parses the real nested contents while this codec sees an
> empty element followed by stray *TLVs* — the two layers disagree about the
> message. Without a second parser in the path it degrades to a
> spec-conformance defect.
