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:
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
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.
CERT Advisory CA-2003-10: Integer overflow in Sun RPC XDR
Vulnerability Note VU#516825: Integer overflow in Sun RPC
XDR library routines
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.
CERT Advisory CA-2003-11: Multiple Vulnerabilities in
Lotus Notes and Domino
Vulnerability Note VU#206361: Lotus iNotes vulnerable to
buffer overflow via PresetFields FolderName field
Vulnerability Note VU#355169: Lotus Domino Web Server
vulnerable to denial of service via incomplete POST
Vulnerability Note VU#542873: Lotus iNotes vulnerable to
buffer overflow via PresetFields s_ViewName field
Vulnerability Note VU#772817: Lotus Domino Web Server
vulnerable to buffer overflow via non-existent
"h_SetReturnURL" parameter with an overly long "Host
Vulnerability Note VU#571297: Lotus Notes and Domino COM
Object Control Handler contains buffer overflow
Vulnerability Note VU#433489: Lotus Domino Server
susceptible to a pre-authentication buffer overflow
Vulnerability Note VU#411489: Lotus Domino Web Retriever
contains a buffer overflow vulnerability
Vulnerability Note VU#583184: Lotus Domino R5 Server
Family contains multiple vulnerabilities in LDAP handling
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
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.
CERT Advisory CA-2003-12: Buffer Overflow in Sendmail
Vulnerability Note VU#897604: Sendmail address parsing
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
CERT Advisory CA-2003-13: Multiple Vulnerabilities in
Vulnerability Note VU#139129: Heap overflow in Snort
Vulnerability Note VU#916785: Buffer overflow in Snort
