Detail
| While performing an audit of MySQL e-matters found several problems: * signed/unsigned problem in COM_TABLE_DUMP Two sizes were taken as signed integers from a request and then cast to unsigned integers without checking for negative numbers. Since the resulting numbers where used for a memcpy() operation this could lead to memory corruption. * Password length handling in COM_CHANGE_USER When re-authenticating to a different user MySQL did not perform all checks that are performed on initial authentication. This created two problems: * it allowed for single-character password brute forcing (as was fixed in February 2000 for initial login) which could be used by a normal user to gain root privileges to the database * it was possible to overflow the password buffer and force the server to execute arbitrary code * read_rows() overflow in libmysqlclient When processing the rows returned by a SQL server there was no check for overly large rows or terminating NUL characters. This can be used to exploit SQL clients if they connect to a compromised MySQL server. * read_one_row() overflow in libmysqlclient When processing a row as returned by a SQL server the returned field sizes were not verified. This can be used to exploit SQL clients if they connect to a compromised MySQL server. For Debian GNU/Linux 3.0/woody this has been fixed in version 3.23.49-8.2 and version 3.22.32-6.3 for Debian GNU/Linux 2.2/potato. We recommend that you upgrade your mysql packages as soon as possible. |

| Id | Description |
|---|---|
| 8889 | MySQL COM_TABLE_DUMP Package Negative Integer DoS MySQL contains a flaw that may allow a remote denial of service. The issue is triggered when a specially crafted packet is sent containing negative values that are not validated occurs, and will result in loss of availability for the service. |
| 8888 | MySQL COM_CHANGE_USER Command Long Repsonse Overflow A remote overflow exists in MySQL. The MySQL fails to validate the password variable in the COM_CHANGE_USER command resulting in a stack overflow. With a specially crafted request, an attacker can cause overwrite the saved instruction pointer resulting in a loss of integrity. |
| 8887 | MySQL COM_CHANGE_USER Command One Character Password Brute Force MySQL 4.0.5a contains a flaw in the COM_CHANGE_USER function that may lead to an unauthorized password exposure. It is possible to gain access to another user's credentials, such as root, by brute-force guessing only the first character of the target's password. |
| 8886 | MySQL libmysqlclient Library read_one_row Overflow |
| 8885 | MySQL libmysqlclient Library read_rows Overflow |
