Integer Overflow vulnerability in RELIC before commit 34580d840469361ba9b5f001361cad659687b9ab, allows attackers to execute arbitrary code, cause a denial of service, and escalate privileges when calling realloc function in bn_grow function.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
