Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in uv__idna_toascii() function in libuv, which is used to convert strings to ASCII. A remote attacker can force the application to resolve a specially crafted hostname, trigger an out-of-bounds read error and gain access to sensitive information or perform a denial of service (DoS) attack.
