Linux Advisory Watch is a comprehensive newsletter that outlines the
security vulnerabilities that have been announced throughout the week.It
includes pointers to updated packages and descriptions of each
vulnerability.

This week, advisories were released for fetchmail, sendmail, xinetd,
bugzilla, apache-contrib, uucp, and xloadimage.  The vendors include
Caldera, Conectiva, Red Hat, and SuSE.

It has been a tragic week.  Our own Dave Wreski writes, "Today's events
mark more than a display of courage by Americans, an effort to exact
retribution on those who committed this senseless act, and how this
country will be changed as a result. It directly impacts us all on an
international scale as individual architects of the global Internet."

+---------------------------------+
|  fetchmail                      | ----------------------------//
+---------------------------------+

Fetchmail versions up to 5.8.9 are susceptible to remote attacks from
malicious servers.  When fetchmail attempts to create an index of messages
in the remote mailbox being polled, it uses index numbers sent by the
server as an index into an internal array. If a server sends fetchmail a
negative number, fetchmail will attempt to write data outside the bounds
of the array.

  Red Hat 7.1: i386: 

  ftp://updates.redhat.com/7.1/en/os/i386/ 
  fetchmail-5.9.0-0.7.1.i386.rpm

+---------------------------------+
|  sendmail                       | ----------------------------//
+---------------------------------+

An input validation error in the debugging functionality of all currently
released versions of sendmail can enable a local user to gain root access.  
New packages that fix this problem are available for Red Hat Linux 5.2,
6.2, 7.0, and 7.1.

  Red Hat Vendor Advisory: 
  http://www.linuxsecurity.com/advisories/redhat_advisory-1602.html


  
+---------------------------------+
|  xinetd                         | ----------------------------//
+---------------------------------+

A security audit has been done by Solar Designer on xinetd, and the
results are now being made available as a preemptive measure. Also,
memsetting too much memory to 0 would eventually lead to segfaults when
executing services. This internal bug was fixed.

  Red Hat 7.1: i386: 

  ftp://updates.redhat.com/7.1/en/os/i386/ 
  xinetd-2.3.3-1.i386.rpm

  Red Hat Vendor Advisory:

+---------------------------------+
|  bugzilla                       | ----------------------------//
+---------------------------------+

The updated bugzilla package fixes numerous security issues which were
present in previous releases of bugzilla.

  Red Hat 7.1  i386:

  Red Hat Vendor Advisory: 
  http://www.linuxsecurity.com/advisories/redhat_advisory-1604.html


  
+---------------------------------+
|  apache-contrib                 | ----------------------------//
+---------------------------------+

The Apache module mod_auth_mysql 1.4,which is shipped since SuSE Linux
7.1, was found vulnerable to possible bypass authentication by MySQL
command injection.  An adversary could insert MySQL commands along with a
password and these commands will be interpreted by MySQL while
mod_auth_mysql is doing the password lookup in the database. A positive
authentication could be returned.

  SuSE-7.2 

  ftp://ftp.suse.com/pub/suse/i386/update/7.2/n2/ 
  apache-contrib-1.0.9-94.i386.rpm 
  7c84f6c3f8aaf2b96a312fea4d36abce 

  SuSE Vendor Advisory: 
  http://www.linuxsecurity.com/advisories/suse_advisory-1605.html

  
  
+---------------------------------+
|  uucp                           | ----------------------------//
+---------------------------------+

There is a argument handling problem which allows a local attacker to gain
access to the uucp group. Using this access the attacker could use badly
written scripts to gain access to the root account.

  PLEASE SEE VENDOR ADVISORY

  http://www.linuxsecurity.com/advisories/caldera_advisory-1606.html 

  Conectiva Vendor Advisory: 
  http://www.linuxsecurity.com/advisories/other_advisory-1608.html



+---------------------------------+
|  xloadimage                     | ----------------------------//
+---------------------------------+

A buffer overflow exists in xli due to missing boundary checks.  This
could be triggered by an external attacker to execute commands on the
victim's machine.  An exploit is publically available. xli is an image
viewer that is used by Netscape's plugger to display TIFF, PNG, and
Sun-Raster images.
