"the Apache Spamassassin project reports :

In Apache SpamAssassin, using HTML::Parser, we setup an object and
hook into the begin and end tag event handlers In both cases, the
'open' event is immediately followed by a 'close' event - even if the
tag *does not* close in the HTML being parsed.

Because of this, we are missing the 'text' event to deal with the
object normally. This can cause carefully crafted emails that might
take more scan time than expected leading to a Denial of Service.

Fix a reliance on '.' in @INC in one configuration script. Whether
this can be exploited in any way is uncertain.

Fix a potential Remote Code Execution bug with the PDFInfo plugin.
Thanks to cPanel Security Team for their report of this issue.

Fourth, this release fixes a local user code injection in the meta
rule syntax. Thanks again to cPanel Security Team for their report of
this issue."
