For future reference: 

Please be cool -- first notify the authors of the
package before posting to bugtraq. This is the
generally accepted etiquette for handling the
security-related bugs and allows developers to
come up with the fix before the problem is widely
known.

Here is the fix for the arbitrary remote execution
with httpd-user rights. Place this file in the
squirrelmail/plugins/squirrelspell directory and
execute it to fix the vulnerability.

--- begin sqspell_security_fix.sh ---
#!/bin/sh
sed "s/.mod.php/.mod/g" sqspell_interface.php > tmp.1
sed "s/.mod.php/.mod/g" sqspell_options.php > tmp.2
mv -f tmp.1 sqspell_interface.php
mv -f tmp.2 sqspell_options.php
cd modules
for FILE in *.mod.php; do 
        NEWFILE=`echo $FILE | sed 's/.php//'`
        mv $FILE $NEWFILE
done
--- end sqspell_security_fix.sh ---

squirrelmail-1.2.4 will contain the fix and should
be released shortly.
