- Vendor Statements

The upstream fix for this issue is not backwards compatible and introduces an ABI change not allowed in Red Hat Enterprise Linux. Therefore, there is no plan to address this problem directly in cyrus-sasl packages. All applications shipped in Red Hat Enterprise Linux and using affected sasl_encode64() function were investigated and patched if their use of the function could have security consequences. See following bug report for further details: https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2009-0688#c20
