Successful exploitation of this vulnerability requires MySQL to be built on a system with a library that allows "memcmp()" to return a value outside of the -128 through 127 range (e.g. sse-optimized glibc). NOTE: Vendor binaries are reportedly not affected. The security issue is reported in versions prior to 5.1.63 and 5.5.25. 2) An unspecified error exists. No further information is currently available. This vulnerability is reported in versions prior to 5.1.63. SOLUTION: Update to version 5.1.63 or 5.5.25. PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.
