Sympa wwsympa do_search_list Overflow DoS

Vulnerability Assessment Summary
Checks for sympa version

Detailed Explanation for this Vulnerability Assessment

The remote host is running SYMPA, an open source mailing list software.

This version of Sympa has a flaw in one of it's scripts (wwsympa.pl) which
would permit a remote attacker to overflow the sympa server. Specifically,
within the cgi script wwsympa.pl is a do_search_list function which fails to perform
bounds checking. A possible hacker, passing a specially formatted long string
to this function, would be able to crash the remote sympa server. At the
time of this writing, the attack is only known to cause a Denial of Service
(DoS).

Solution : Update to version 4.1.2 or newer
