a potential NPD in source file src/proto_http.c
Hi, I found a potential null pointer dereference bug in the project source code of libshout, and I have shown the execution sequence of the program that may generate the bug on the graph below. The red text illustrates the steps that generate the bug, the file path can be seen in the blue framed section.
Although the code shown is for the latest but is still exist in current version.
What I'm confused about is, some empty judgment operation to return value of httpp_getvar can be found in some code snippets of the libshout project, so I'm not sure if the context of this snippet can assert that the call-statement won't return null, if so please give me some hints.thank you for checking if this bug is true.
