Static Analysis Reports

Hi, I checked the code with a static analyzer and UBSAN and have some findings to report.

Tinyproxy version

Git Master

In hsearch.c:

• hsearch.c:85:36: runtime error: applying zero offset to null pointer
• hsearch.c:85:49: applying non-zero offset 24 to null pointer

in reqs.c:

• reqs.c:349:15: sscanf() sscanf has no field width limits and may crash depending on the input
• reqs.c:380:48: Passing NULL as the last typed argument to a variadic function leads to UB.

Do these issues need to be addressed?

Kind regards and thanks in advance
