Description

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

The vulnerability exists due to an error in AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimized implementation.

A remote attacker can gain access to potentially sensitive information.
