Background

Cyrus-SASL is an implementation of the Simple Authentication and Security Layer.

Description

Cyrus-SASL contains a remote buffer overflow in the digestmda5.c file. Additionally, under certain conditions it is possible for a local user to exploit a vulnerability in the way the SASL_PATH environment variable is honored (CAN-2004-0884).

Impact

An attacker might be able to execute arbitrary code with the Effective ID of the application calling the Cyrus-SASL libraries.

Workaround

There is no known workaround at this time.

Resolution

All Cyrus-SASL users should upgrade to the latest stable version:

 # emerge sync
 
 # emerge -pv "&gt;=dev-libs/cyrus-sasl-2.1.18-r2"
 # emerge "&gt;=dev-libs/cyrus-sasl-2.1.18-r2"
