In general this means that there are no known serious bugs, except for those marked as feature requests, that no bugs were fixed since last release that caused a notable code changes, and that we believe the code is ready for general usage (based on bug inflow). **For a description of** [**MariaDB 5.5**](/docs/release-notes/community-server/old-releases/5.5/changes-improvements-in-mariadb-5-5.md) **see the**[**What is MariaDB 5.5**](/docs/release-notes/community-server/old-releases/5.5/changes-improvements-in-mariadb-5-5.md) **page.** For a list of changes made in [MariaDB 5.5.27](/docs/release-notes/community-server/old-releases/5.5/5.5.27.md), with links to detailed information on each push, see the [MariaDB 5.5.27 Changelog](/docs/release-notes/community-server/changelogs/changelogs-mariadb-55-series/mariadb-5527-changelog.md). In most respects [MariaDB](https://mariadb.com/docs/server/) will work exactly as MySQL: all commands, interfaces, libraries and APIs that exist in MySQL also exist in MariaDB. ## Includes [MariaDB 5.3.8](/docs/release-notes/community-server/old-releases/5.3/5.3.8.md) and MySQL 5.5.27 [MariaDB 5.5.27](/docs/release-notes/community-server/old-releases/5.5/5.5.27.md) includes [MariaDB 5.3.8](/docs/release-notes/community-server/old-releases/5.3/5.3.8.md) and MySQL 5.5.27. See the [MariaDB 5.3.8](/docs/release-notes/community-server/old-releases/5.3/5.3.8.md)[Release Notes](/docs/release-notes/community-server/old-releases/5.3/5.3.8.md) and [Changelog](/docs/release-notes/community-server/changelogs/changelogs-mariadb-53-series/mariadb-538-changelog.md) for more information on the changes in [MariaDB 5.3.8](/docs/release-notes/community-server/old-releases/5.3/5.3.8.md). See [Changes in MySQL 5.5.27](https://dev.mysql.com/doc/refman/5.5/en/news-5-5-27.html) for what changed between this and previous MySQL versions. ## Includes XtraDB from Percona-Server-5.5.27-rel28.1 For [MariaDB 5.5.27](/docs/release-notes/community-server/old-releases/5.5/5.5.27.md), we've merged in XtraDB from Percona Server Percona-Server-5.5.27-rel28.0 and 5.5.27-rel28.1. See the Percona Server [5.5.27-28.0](https://www.percona.com/doc/percona-server/5.5/release-notes/Percona-Server-5.5.27-28.0.html) and [5.5.27-28.1](https://www.percona.com/doc/percona-server/5.5/release-notes/Percona-Server-5.5.27-28.1.html) release notes for more information. ## Alternative Linux binaries In this version of MariaDB we are starting to provide alternative Linux binaries built on a different build machine with a different build toolchain. Binaries created on this box require at least GLIBC\_2.14. For continuity, we are still providing binaries built with the same toolchain as previous releases. The alternative binaries have a "(GLIBC\_2.14)" label to distinguish them from the others. ## Fixes and Performance Enhancements This release includes fixes for the following security vulnerabilities: * [CVE-2012-3163](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3163) * [CVE-2012-3158](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3158) * [CVE-2012-3177](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3177) * [CVE-2012-3150](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3150) * [CVE-2012-3197](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3197) * [CVE-2013-1548](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-1548) * [CVE-2012-3166](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3166) * [CVE-2012-3173](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3173) * [CVE-2012-3167](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3167) This release fixes numerous cases of the incorrect identifier quoting in the replication code. They were open [SQL injection](https://en.wikipedia.org/wiki/SQL_injection) vulnerabilities, that allowed, to a certain extent, to bypass the database privilege system and modify the data, that one was granted no access to. See [MDEV-382](https://jira.mariadb.org/browse/MDEV-382) for details. ([CVE-2012-4414](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-4414)) Additionally, 5.5.27 includes several other bug fixes and performance enhancements. See the [MariaDB 5.5.27 Changelog](/docs/release-notes/community-server/changelogs/changelogs-mariadb-55-series/mariadb-5527-changelog.md) for full details.
