FINAL RESULTS:
data/curlpp-0.8.1/include/curlpp/cURLpp.hpp:146:14: [3] (buffer) getenv:
Environment variables are untrustable input if they can be set by an
attacker. They can have any content and length, and the same variable can
be set more than once (CWE-807, CWE-20). Check environment variables
carefully before using them.
std::string getenv(const std::string & name);
data/curlpp-0.8.1/src/curlpp/cURLpp.cpp:80:9: [3] (buffer) getenv:
Environment variables are untrustable input if they can be set by an
attacker. They can have any content and length, and the same variable can
be set more than once (CWE-807, CWE-20). Check environment variables
carefully before using them.
curlpp::getenv(const std::string & name)
data/curlpp-0.8.1/src/curlpp/cURLpp.cpp:83:14: [3] (buffer) curl_getenv:
Environment variables are untrustable input if they can be set by an
attacker. They can have any content and length, and the same variable can
be set more than once (CWE-807, CWE-20). Check environment variables
carefully before using them.
char* p = curl_getenv(name.c_str());
data/curlpp-0.8.1/examples/example02.cpp:72:2: [2] (buffer) char:
Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.
char buf[50];
data/curlpp-0.8.1/examples/example02.cpp:80:3: [2] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf. Risk is low because the source has a constant maximum length.
sprintf(buf, "Content-Length: %d", size);
data/curlpp-0.8.1/examples/example05.cpp:66:3: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy(&(m_pBuffer[m_Size]), ptr, realsize);
data/curlpp-0.8.1/examples/example06.cpp:80:3: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy(&(m_pBuffer[m_Size]), ptr, realsize);
data/curlpp-0.8.1/examples/example10.cpp:63:16: [2] (misc) fopen:
Check when opening files - can an attacker redirect it (via symlinks),
force the opening of special file type (e.g., device files), move things
around to create a race condition, control its ancestors, or change its
contents? (CWE-362).
FILE * file = fopen(filename, "w");
data/curlpp-0.8.1/examples/example11.cpp:78:11: [2] (misc) fopen:
Check when opening files - can an attacker redirect it (via symlinks),
force the opening of special file type (e.g., device files), move things
around to create a race condition, control its ancestors, or change its
contents? (CWE-362).
file = fopen(filename, "wb");
data/curlpp-0.8.1/examples/example21.cpp:55:3: [2] (buffer) char:
Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.
char buf[50];
data/curlpp-0.8.1/examples/example21.cpp:63:7: [2] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf. Risk is low because the source has a constant maximum length.
sprintf(buf, "Content-Length: %d", size);
data/curlpp-0.8.1/include/curlpp/internal/CurlHandle.hpp:180:3: [2] (buffer) char:
Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.
char mErrorBuffer[CURL_ERROR_SIZE + 1];
data/curlpp-0.8.1/examples/example02.cpp:52:2: [1] (buffer) strncpy:
Easily used incorrectly; doesn't always \0-terminate or check for invalid
pointers [MS-banned] (CWE-120).
strncpy(buffer, data, size * nitems);
data/curlpp-0.8.1/examples/example02.cpp:70:13: [1] (buffer) strlen:
Does not handle strings that are not \0-terminated; if given one it may
perform an over-read (it could cause a crash if unprotected) (CWE-126).
int size = strlen(data);
data/curlpp-0.8.1/src/curlpp/Multi.cpp:89:31: [1] (buffer) read:
Check buffer boundaries if used in a loop including recursive loops
(CWE-120, CWE-20).
curlpp::Multi::fdset(fd_set * read, fd_set * write, fd_set * exc, int * max)
data/curlpp-0.8.1/src/curlpp/Multi.cpp:91:51: [1] (buffer) read:
Check buffer boundaries if used in a loop including recursive loops
(CWE-120, CWE-20).
CURLMcode code = curl_multi_fdset(mMultiHandle, read, write, exc, max);
data/curlpp-0.8.1/src/curlpp/internal/OptionSetter.cpp:77:11: [1] (buffer) read:
Check buffer boundaries if used in a loop including recursive loops
(CWE-120, CWE-20).
stream->read(buffer, static_cast<std::streamsize>(size * nitems));
