As you can see, we have a check for integer overflow on the size of the allocation. Because we are using pure-capability CHERI, even without this check, it’s not possible to access the allocation beyond its bounds. That’s because whatever size the heap will allocate, the exact bounds ...
(This problem is discovered when UBSAN is enabled) on openjpeg 2.3 (latest version): there is a integer overflow in the opj_t1_encode_cblks function (src/lib/openjp2/t1.c), which could be triggered by the POC. POC address: https://github...

Note that the code uses calloc, rather than malloc, as doing so avoids the possibility of integer overflow in the multiplication to calculate the size bytes.Migrating Your Code In the last nine months, we've migrated the Windows® code base and the developer division (Visual ...
Integer division by zero (FPE_INTDIV) and integer overflow (FPE_INTOVF) are also included among the SIGFPE types, but because they are not IEEE floating point exceptions you cannot install handlers for them via ieee_handler. (You can install handlers for these SIGFPE types via sigfpe(3); ...

at the expense of some heap space. This one also aborts in wcscpy_s if there isn't enough space, but that should only occur if you have a logic bug. Note that the code uses calloc, rather than malloc, as doing so avoids the possibility of integer overflow in the multiplication to cal...
