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 ========== There is no known workaround at this time. Resolution ========== 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" References ========== [ 1 ] CAN-2004-0884 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0884 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200410-05.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
