Subject: RE: libupnp buffer overflows

You can find the list of source code commits for the 1.6.16 here:;a=log;h=01d7c05fb882bb1904f5022a33eef8a68d8b8bdc.

Moreover, the most important bug fixes have been added in the tracker:

To sum up, most of the issues were about memory leaks (, a few of them were about security like an out of bound access (, classified as CWE-119 by Coverity). However, most of the other "security" changes have been made to:
	- replace strcpy or sprint by strncpy or snprintf as using sprintf is seen as a defect by coverity (CWE-676)
 	- remove implicit integer conversion between unsigned and signed (seen as CWE-681 by Coverity)

Fabrice replied: 
Those issues were found by Coverity ( Coverity affects CWE identifiers like CWE-170 but I haven't kept the CWE identifiers of all the fixed bugs.

Did you Fabrice verify if these had security impact? I can try to help if needed.
