Cyrus-SASL: Buffer overflow and SASL

Cyrus-SASL: Buffer overflow and SASL_PATH vulnerabilities Cyrus-SASL contains two vulnerabilities that might allow an attacker to completely compromise the vulnerable system. Cyrus-SASL 2004-10-07 2006-05-22 56016 remote 2.1.18-r2 2.1.18-r1

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

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).

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

There is no known workaround at this time.

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


    # emerge sync
    
    # emerge -pv ">=dev-libs/cyrus-sasl-2.1.18-r2"
    # emerge ">=dev-libs/cyrus-sasl-2.1.18-r2"
