Multiple buffer overflows in the CMU Cyrus SASL library before 2.1.23 might allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via strings that are used as input to the sasl_encode64 function in lib/saslutil.c.

Security readout for executives and security teams

CVE-2009-0688 is a memory-safety flaw in CMU Cyrus SASL before 2.1.23. A remote attacker might cause a service crash or potentially run code through crafted input handled by the library. Business risk depends on where older Cyrus SASL packages remain in use. Exposure is most likely on legacy systems or appliances using CMU Cyrus SASL before 2.1.23, especially network-facing services that rely on SASL authentication libraries. The bundle does not enumerate specific application products or affected CPEs. Treat this as a legacy exposure cleanup item with high impact potential. It is not KEV-listed in the provided evidence, but remote code execution language and broad library reuse justify prioritizing exposed or unsupported systems. Mitigation focus: Upgrade CMU Cyrus SASL to 2.1.23 or a vendor-fixed package.; Check OS vendor advisories for supported backported fixes.; Prioritize internet-facing authentication, mail, LDAP, and messaging services..
