Description:
Avaya has acknowledged a security issue in various Avaya products, which can be exploited by malicious users to bypass certain security restrictions.

The problem is that util-linux login omits "pam_acct_mgmt" and "chauth_tok" when authentication is skipped (e.g. with a valid Kerberos ticket) and can be exploited by malicious users to bypass certain access policies.

The security issue affects the following products:
* Avaya Communication Manager (CM 2.x, 3.x, 4.x)
* Avaya Messaging Storage Server (MSS 3.x)
* Avaya Message Networking (all versions)
* Avaya CCS/SES (all versions)
* Avaya AES (AES 4.0)

Solution:
The vendor recommends that local and network access to the affected systems be restricted until an update is available.
