Now we just found a small problem in bluez sdp.c. When we are creating service record that contains SDP_SEQ and its (SEQ) binary size more then 254 bytes we get *** stack smashing detected *** error. For tests SDP_SEQ containing 253 Null elements has been used. Stack: [0xb512f000,0xb5180000), sp=0xb517e930, free space=318k Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) C [libbluetooth.so.2+0xace2] sdp_append_to_buf+0x22 C [libbluetooth.so.2+0xde08] sdp_append_to_pdu+0x98 My entry point to the library is sdp_extract_pdu Tested on Fedora 7 2.6.21 i386, bluez-libs 3.9 I was looking at the source code for sdp.c 3.25 and can't see any related changes. The code creating the test is in java and it call function in BlueCoveBlueZ_Tests.c How should I approach to fix this bluez?
