[TYPO3-english] class.t3lib_htmlmail.php ERROR - canary mismatch on efree() - heap overflow detected

[Georg Schönweger]

Hi,

i just saw in my Logs that i have the same error message with
sr_feuser_register (2.5.25).
Im using Ubuntu 9.10 with PHP Version 5.2.10 and Suhosin Patch 0.9.7
Typo3 4.2.12

did you find any solution for this?

[Thu May 13 14:43:29 2010] [error] [client 87.12.93.26] ALERT - canary
mismatch on efree() - heap overflow detected (attacker '87.12.93.26',
file
'/usr/local/nginx/html/typo3_src-4.2.12/t3lib/class.t3lib_htmlmail.php',
line 718), referer: http://www.snillo.it/my-account/registrati/

The error occurs randomly, but only with sr_feuser_register

kind regards,
Georg Schönweger
