Background ==========
Cyrus-SASL is an implementation of the Simple Authentication and Security Layer.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/cyrus-sasl <= 2.1.18-r1 >= 2.1.18-r2
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 ==========
