Description

This security bulletin contains information about 1 security vulnerability.


1) Input validation error (CVE-ID: CVE-2020-28362)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in a number of math/big.Int methods (Div, Exp, DivMod, Quo, Rem, QuoRem, Mod, ModInverse, ModSqrt, Jacobi, and GCD). A remote attacker can pass large input data to the application, specifically as divisor or modulo argument larger than 3168 bits (on 32-bit architectures) or 6336 bits (on 64-bit architectures).
