84298 - Server side sorting with sorting order creates wrong PDU

Status: RESOLVED WONTFIX

(Directory Graveyard :: LDAP Java SDK, defect)

Description

[Uwe Krueger]

We use LDAP JAVA SDK 4.1

The following PDU was sent if I use "reverse order = true" when creating the
LDAPSortKey (2 parameter constructor).

PDUs
          controls_V3 = ARRAY OF 1 {
            ELEM[0] = STRUCT LDAP_Ctrl_V3 {
              bit_mask = 0xc0 ;
              controlType = 22 char value(s)
                0000  31 2e 32 2e 38 34 30 2e 31 31 33 35  1.2.840.1135
                000C  35 36 2e 31 2e 34 2e 34 37 33        56.1.4.473..
              critity = FALSE ;
              controlVal_V3 = 21 char value(s)
                0000  30 13 30 11 04 0b 64 65 73 63 72 69  0.0...descri
                000C  70 74 69 6f 6e 81 02 00 81           ption.......
            }
          }

decoded controlVal_V3:

1 T=30 - class = UNIVERSAL : constructed : tag = SEQUENCE {
   L=13 - 19
 2   T=30 - class = UNIVERSAL : constructed : tag = SEQUENCE {
     L=11 - 17
       T=04 - class = UNIVERSAL : primitive : tag = OCTETSTRING 
       L=0b - 11
       V=64 65 73 63 72 69 70 74 69 6f   
         6e                              
       T=81 - class = CONTEXT SPECIFIC : primitive : tag = [1] 
       L=02 - 2     <<< ERROR
       V=00 81      <<< ERROR
 2   }
 1 }

The Error was within the last 3 bytes (BOOLEAN)
This BOOLEAN was coded 2 Bytes long. 
It's a wrong BER BOOLEAN coding!
According to the RFC the BOOLEAN value has to be coded with the least possible 
length which was 1 Byte in this case.

a valid ending were:
      T=81 - class = CONTEXT SPECIFIC : primitive : tag = [1] 
      L=01 - 1
      V=ff

Uwe Krueger

Reassigned to Miodrag (Java LDAP SDK lead engineer).  Please post a patch if you
have one.

By the way, which directory server was used to expose the bug?

Comment 3

[Uwe Krueger]

@ Mark:  Sorry - no patch available here

@ Miodrag: Directory Server = Siemens  DirX 6.0
