Defects found in static analysis

[Alisha]

I am using libfcgi-2.4.0 armhf version in my application. Which is available here https://packages.ubuntu.com/trusty/armhf/libfcgi-dev

We run Coverity Scan on code and we have found the following defects:

1. File os_unix.c
     line 295 and 398
     defect : Copy into fixed size buffer. The string operation will write past the end of the fixed-size
               destination buffer if the source buffer is too large. You might overrun the 1024-character
               fixed-size string host by copying bindPath without checking the length

2. File fcgiapp.c
    line 600
    defect : Out-of-bounds access. Access of memory not owned by this buffer may cause crashes or incorrect
              computations. Overrunning buffer pointed to by charPtrArg of 7 bytes by passing it to a
              function which accesses it at byte offset 999998 using argument precision (which evaluates to
              999999).

3. File fcgiapp.c
     line 1471
     defect : Dereference null return value. If the function actually returns a null value, a null pointer
              dereference will occur. Dereferencing strchr(name, 61), which is known to be NULL.

4. File fcgio.cpp
    line 157 and 165
    defect : Operands don't affect result. The expression's value does not depend on the operands; often,
              this represents an inadvertent logic error. result_independent_of_operands: n > 2147483647 is
              always false regardless of the values of its operands. This occurs as the logical operand of if

Please let me know if these issues will be getting fixed in coming versions.

Hello

Thanks for taking the time to report this bug; this kind of analysis is probably best fed back to the actual upstream project, rather than to a distribution. Upstream development happens here:

  https://github.com/FastCGI-Archives/fcgi2

Marking this bug as a won't fix for Ubuntu.
