Wim Taymans 026ae3af7a security: add bounds check for exec argv array in filter-graph
Memory Safety: Medium

The do_exec() function in the filter-graph builtin plugin parses a
JSON array of arguments into a fixed-size argv[512] stack buffer
without checking whether argc exceeds the array bounds. A crafted
filter-graph configuration with more than 511 arguments would cause
a stack buffer overflow.

Add a bounds check before each insertion to ensure argc stays within
the array limits, reserving space for the NULL terminator.
