    Package        : mariadb-10.5
    Version        : 1:10.5.29-0+deb11u1
    CVE ID         : CVE-2025-30693 CVE-2025-30722
    Debian Bug     : 1099515 1105976

    Vulnerabilities was discovered in MariaDB, a SQL database server
    compatible with MySQL.

    CVE-2025-30693

        Easily exploitable vulnerability allows high privileged
        attacker with network access via multiple protocols to
        compromise MariaDB Server. Successful attacks of this
        vulnerability can result in unauthorized ability to
        cause a hang or frequently repeatable crash (complete DoS)
        of MariaDB Server as well as unauthorized update, insert or
        delete access to some of MariaDB Server accessible data.

    CVE-2025-30722

        Difficult to exploit vulnerability allows low
        privileged attacker with network access via multiple
        protocols to compromise MariaDB Client. Successful attacks
        of this vulnerability can result in unauthorized access
        to critical data or complete access to all MariaDB Client
        accessible data as well as unauthorized update, insert
        or delete access to some of MariaDB Client accessible data


    For Debian 11 bullseye, these problems have been fixed in version
    1:10.5.29-0+deb11u1.


    This update also includes a NEWS entry about CVE-2025-30693:

      Fix of CVE-2025-30693, need to changes data format of innoDB format
      particularly variable-length encoding. Fix replace
      mach_write_compressed() with mach_u64_write_much_compressed(),
      which produces an identical encoding for 32-bit unsigned values.
      Any 64-bit unsigned integer that does not fit in 32 bits would be
      encoded as the octet 0xff followed by two the variable-length
      encoded 32-bit halves of the integer.

      This scheme is not backward compatible with older format, and may
      break external tools, particularly if tools read indexes on
      virtual columns in InnoDB undo log records.


    Additionally, the updates also includes bugfixes through the 10.5 maintenance
    branch, as detailed at: https://mariadb.com/kb/en/mariadb-10-5-29-release-notes/

    We recommend that you upgrade your mariadb-10.5 packages.
