Cyrus-SASL: Buffer overflow and SASL_PATH vulnerabilities
Gentoo Linux Security Advisory

||October 07, 2004

All supported architectures
Cyrus-SASL contains two vulnerabilities that might allow an attacker to
completely compromise the vulnerable system.
Cyrus-SASL is an implementation of the Simple Authentication and
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:
Code Listing 3.1: Resolution
# emerge sync
# emerge -pv ">=dev-libs/cyrus-sasl-2.1.18-r2"
# emerge ">=dev-libs/cyrus-sasl-2.1.18-r2"
