Sympa wwsympa do_search_list Overflow DoS |

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 See also: http://www.sympa.org/ Network Security Threat Level: Medium Networks Security ID: Vulnerability Assessment Copyright: This script is Copyright (C) 2004 David Maciejak |
