CVSS v2.0

5.1

Média

VetorAV:N/AC:H/Au:N/C:P/I:P/A:P
Name of the Vulnerable Software and Affected Versions Oracle MySQL versions 5.1.x through 5.1.62, 5.5.x through 5.5.23, and 5.6.x through 5.6.5 MariaDB versions 5.1.x through 5.1.61, 5.2.x through 5.2.11, 5.3.x through 5.3.5, and 5.5.x through 5.5.22
Description The issue allows remote attackers to bypass authentication by repeatedly authenticating with the same incorrect password, which eventually causes a token comparison to succeed due to an improperly-checked return value. This occurs when running in certain environments with certain implementations of the memcmp function.
Recommendations For Oracle MySQL versions 5.1.x through 5.1.62, update to version 5.1.63 or later. For Oracle MySQL versions 5.5.x through 5.5.23, update to version 5.5.24 or later. For Oracle MySQL versions 5.6.x through 5.6.5, update to version 5.6.6 or later. For MariaDB versions 5.1.x through 5.1.61, update to version 5.1.62 or later. For MariaDB versions 5.2.x through 5.2.11, update to version 5.2.12 or later. For MariaDB versions 5.3.x through 5.3.5, update to version 5.3.6 or later. For MariaDB versions 5.5.x through 5.5.22, update to version 5.5.23 or later.
