**Issue Overview:**
Integer overflow in exec/totemcrypto.c:authenticate_nss_2_3() function
An integer overflow leading to an out-of-bound read was found in authenticate_nss_2_3() in Corosync. An attacker could craft a malicious packet that would lead to a denial of service.(CVE-2018-1084)
**Affected Packages:**
