CERT Summary CS-2003-02

   June 3, 2003

   Each quarter, the CERT Coordination Center (CERT/CC) issues the CERT
   Summary to draw attention to the types of attacks reported to our
   incident response team, as well as other noteworthy incident and
   vulnerability information. The summary includes pointers to sources of
   information for dealing with the problems.

   Past CERT summaries are available from:

   ______________________________________________________________________

Recent Activity

   Since the last regularly scheduled CERT summary, issued in March 2003
   (CS-2003-01), we have seen an integer overflow vulnerability within
   Sun's XDR Library, multiple vulnerabilities in Lotus Notes and Domino
   Server, a buffer overflow vulnerability in Sendmail, and multiple
   vulnerabilities within Snort's preprocessors.

   For more current information on activity being reported to the
   CERT/CC, please visit the CERT/CC Current Activity page. The Current
   Activity page is a regularly updated summary of the most frequent,
   high-impact types of security incidents and vulnerabilities being
   reported to the CERT/CC. The information on the Current Activity page
   is reviewed and updated as reporting trends change.

          CERT/CC Current Activity
          http://www.cert.org/current/current_activity.html

    1. Integer overflow in Sun RPC XDR library routines

       An integer overflow vulnerability exists in the xdrmem_getbytes()
       function distributed as part of the Sun Microsystems XDR library.
       This overflow may allow a remote attacker to execute arbitrary
       code on the victim machine.

                library routines
                http://www.cert.org/advisories/CA-2003-10.html

                Vulnerability Note VU#516825: Integer overflow in Sun RPC
                XDR library routines
                http://www.kb.cert.org/vuls/id/516825

    2. Multiple Vulnerabilities in Lotus Notes and Domino

       Multiple vulnerabilities had been reported to affect Lotus Notes
       clients and Domino servers. Due to the confusion surrounding these
       vulnerabilities we released an advisory to clairfy the details of
       the vulnerabilities, the versions affected, and the patches that
       resolve these issues.

                Lotus Notes and Domino
                http://www.cert.org/advisories/CA-2003-11.html

                Vulnerability Note VU#206361: Lotus iNotes vulnerable to
                buffer overflow via PresetFields FolderName field
                http://www.kb.cert.org/vuls/id/206361

                Vulnerability Note VU#542873: Lotus iNotes vulnerable to
                buffer overflow via PresetFields s_ViewName field
                http://www.kb.cert.org/vuls/id/542873

                Vulnerability Note VU#772817: Lotus Domino Web Server
                vulnerable to buffer overflow via non-existent
                "h_SetReturnURL" parameter with an overly long "Host
                Header" field

                Family contains multiple vulnerabilities in LDAP handling
                code
                http://www.kb.cert.org/vuls/id/583184

    3. Buffer Overflow in Sendmail

       There is a remotely exploitable vulnerability in sendmail that
       could allow an attacker to gain control of a vulnerable sendmail
       server.

       Due to a variable type conversion problem, sendmail may not
       adequately check the length of email address tokens. A specially
       crafted email message could trigger a stack overflow.

                buffer overflow
                http://www.kb.cert.org/vuls/id/897604

    4. Multiple Vulnerabilities in Snort Preprocessors

       There are two vulnerabilities in the Snort Intrusion Detection
       System, each in a separate preprocessor module. Both
       vulnerabilities allow remote attackers to execute arbitrary code
       with the privileges of the user running Snort, typically root
