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.

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
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.

Vulnerability Note VU#583184: Lotus Domino R5 Server
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
