[Bluez-devel] Possible bug in sdp.c

[Pedro Monjo Florit <pmonjo2000@yahoo.com>]

Hi,

I have seen what *may* be a possible bug in sdp.c. If there is an error 
in a SDP PDU sent by a bluetooth device, it seems that the SDP parsing 
code in sdp.c enters an infinite loop filling syslog with the following 
message: "Unknown sequence type, aborting".

I have been tracking down the cause and I have found where the problem 
might be. The function sdp_extract_seqtype() may return 0 in case of 
unrecognized data, but this case does not seem to be handled in the 
calls to this function (for example, in sdp_service_search_attr_req() or 
in sdp_extract_pdu()).

Could anybody tell me whether am I right or wrong? Has anybody seen a 
similar behaviour?

Regards,

Pedro
