DESCRIPTION:
Two vulnerabilities have been reported in TYPO3, which can be
exploited by malicious people to cause a DoS (Denial of Service) and
to conduct SQL injection attacks.

1) An unspecified error when processing an invalid "cHash" parameter
(cache hash) can be exploited to flood caching tables of the
application.

Successful exploitation of this vulnerability requires that
$TYPO3_CONF_VARS['FE']['disableNoCacheParameter'] is set to '1'.

This vulnerability is reported in versions 4.2.0 through 4.5.5.

2) Certain unspecified input passed to the application is not
properly sanitised before being used in prepared queries. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation of this vulnerability requires that two or
more parameters are bound to a prepared query and at least two of
them are controlled by the attacker.

Note: The vendor reports that the TYPO3 Core is not affected by this
vulnerability and that there is currently no known vector with
regards to extensions from the TYPO3 Extension Repository (TER).

This vulnerability is reported in versions 4.5.0 through 4.5.5.

SOLUTION:
Update to versions 4.3.14, 4.4.11, or 4.5.6.

2) Franz G. Jahn
