Bugfix release that fixes an out of bounds read #118. This shouldn't have any security implications.
1.3.0
This release includes a lot of rework in the parser and includes the Cunity unit testing framework, as well as some fixes. I increased the minor version number because there were quite a lot of internal changes.
Features:
- New type for cJSON structs:
cJSON_Invalid
(#108)
Fixes:
- runtime checks for a lot of potential integer overflows
- fix incorrect return in cJSON_PrintBuffered (
cf9d57d56c
) - fix several potential issues found by Coverity
- fix potentially undefined behavior when assigning big numbers to
valueint
(41e2837df1
)- Numbers exceeding
INT_MAX
or lower thanINT_MIN
will be explicitly assigned tovalueint
asINT_MAX
andINT_MIN
respectively (saturation on overflow). - fix the
cJSON_SetNumberValue
macro (87f77274de
), this slightly changes the behavior, see commit message
- Numbers exceeding
Introduce unit tests
Started writing unit tests with the Cunity testing framework. Currently this covers the parser functions.
Also:
- Support for running the tests with Valgrind
- Support for compiling the tests with AddressSanitizer and UndefinedBehaviorSanitizer.
travis.yml
file for running unit tests on travis. (not enabled for the repository yet though #102)
Simplifications
After having unit tests for the parser function in place, I started refactoring the parser functions (as well as others) and making them easier to read and maintain.
- Use
strtod
from the standard library for parsing numbers (0747669972
) - Use goto-fail in several parser functions (#100)
- Rewrite/restructure all of the parsing functions to be easier to understand and have less code paths doing the same as another. (#109)
- Simplify the buffer allocation strategy to always doubling the needed amount (
9f6fa94c91
) - Combined
cJSON_AddItemToObject
andcJSON_AddItemToObjectCS
to one function (cf862d0fed
)
Other changes
- Prevent the usage of incompatible C and header versions via preprocessor directive (
123bb1af7b
) - Let CMake automatically detect compiler flags
- Add new compiler flags (
-Wundef
,-Wswitch-default
,-Wconversion
,-fstack-protector-strong
) (#98) - Change internal sizes from
int
tosize_t
(ecd5678527
) - Change internal strings from
char*
tounsigned char*
(28b9ba4334
) - Add
const
in more places
