CVE-2020-35198: Integer Overflow
First published: Wed May 12 2021(Updated: )
An issue was discovered in Wind River VxWorks 7. The memory allocator has a possible integer overflow in calculating a memory block's size to be allocated by calloc(). As a result, the actual memory allocated is smaller than the buffer size specified by the arguments, leading to memory corruption.
