SigComp: Access violation when decompressing SigComp REGISTER message #218

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.Decompressing a REGISTER message causes an access violation in 
tinySIGCOMP.dll when using a recommended DMS of 8192 (decompress successful 
with DMS of 16384).
2.
3.

What is the expected output? What do you see instead?
Successful decompression using recommended defaults and if size is not correct 
to handle it rather than resulting in an access violation.

What version of the product are you using? On what operating system?
Windows 7; tinySIGCOMP 2.0.0.814

Please provide any additional information below.

Note that the UE sends the REGISTER, then the SUBSCRIBE over UDP; the PUBLISH 
is then sent over TCP because of its size.

I have attached three files
     - MessageLog.pcapng
          o Note that the first PUBLISH caused the exception
     - rfc4465_torture_tests.h
          o Updated to include the necessary hex for replication
     - test_tortures.h
          o Updated to include the necessary 'tests' for replication

The actual exception generated (using torture tests to replicate):

Unhandled exception at 0x0f536b17 (tinySIGCOMP.dll) in test.exe: 0xC0000005: 
Access violation writing location 0x002994ca.

HEX for message chain to exception...
