Security
Brief items
Sometimes it is worthwhile to step back and look at a condensed picture of
the Linux and free software security situation. To that end, we have
thrashed up our security database and produced a big table listing the
vulnerabilities exposed in 2003 and the alerts issued by several major
distributors in response. We turned up over 300 vulnerabilities which
resulted in over 1200 security alerts. In other words, 2003 was a busy
year.
Glancing through the table, one sees that certain packages are responsible
for relatively large numbers of vulnerabilities; these include apache (6
vulnerabilities), ethereal (6), glibc (5), KDE (6), the kernel (6),
and sendmail (5). The kernel wins the prize for the most security alerts,
having been responsible for 47 of them - almost 4% of the total. The full
picture, however, shows a vast number of security problems afflicting a
wide range of packages. The security of our free operating system has some
ground to cover yet before it will be something we can be truly proud of.
Here's the first part of the table:
Those are all of the packages beginning with "A". The full table, in all
its browser-straining glory, can be found on
this page.

David B Harris discovered a problem with mod-auth-shadow, an Apache module
which authenticates users against the system shadow password database,
where the expiration status of the user's account and password were not
enforced. This vulnerability would allow an otherwise authorized user to

The authors of phpgroupware, a web based groupware system written in PHP,
discovered several vulnerabilities. The Common Vulnerabilities and
Exposures project identifies the following problems:
CAN-2004-0016: In the "calendar" module, "save extension" was not enforced
for holiday files. As a result, server-side php scripts may be placed in
directories that then could be accessed remotely and cause the webserver to
execute those. This was resolved by enforcing the extension ".txt" for
holiday files.

improperly sanitized input which allows an attacker to execute arbitrary
commands on the server hosting the bug database. As mitigating factors
these attacks are only available to non-guest users, and accounts for these

André Malo discovered
buffer overflows in the mod_alias and mod_rewrite modules of the Apache

CVE #(s): | CAN-2002-1146

DNS stub resolvers from multiple vendors contain a buffer overflow

denial of service. (See CERT Vulnerability Note
VU#738331)
The BIND 4 and BIND 8.2.x stub resolver libraries, and other libraries such
as glibc 2.2.5 and earlier, libc, and libresolv, uses the maximum buffer
size instead of the actual size when processing a DNS response, which
causes the stub resolvers to read past the actual boundary ("read buffer
overflow"), allowing remote attackers to cause a denial of service

CAN-2003-0776
CAN-2003-0777
CAN-2003-0778
|
| Created: | September 11, 2003 |
Updated: | February 20, 2004 |
| Description: |
Alexander Hvostov, Julien Blache and Aurelien Jarno discovered several
security-related problems in the sane-backends package, which contains
an API library for scanners including a scanning daemon (in the
package libsane) that can be remotely exploited. These problems allow
a remote attacker to cause a segfault fault and/or consume arbitrary
amounts of memory. The attack is successful, even if the attacker's
computer isn't listed in saned.conf.
You are only vulnerable if you actually run saned e.g. in xinetd or
inetd. If the entries in the configuration file of xinetd or inetd
respectively are commented out or do not exist, you are safe.
Try "telnet localhost 6566" on the server that may run saned. If you
get "connection refused" saned is not running and you are safe.
The Common Vulnerabilities and Exposures project identifies the
following problems:
-
CAN-2003-0773: saned checks the identity (IP address) of the remote
host only after the first communication took place (SANE_NET_INIT). So
everyone can send that RPC, even if the remote host is not allowed to
scan (not listed in saned.conf).
-
CAN-2003-0774: saned lacks error checking nearly everywhere in the
code. So connection drops are detected very late. If the drop of the
connection isn't detected, the access to the internal wire buffer leaves
the limits of the allocated memory. So random memory "after" the wire
buffer is read which will be followed by a segmentation fault.
-
CAN-2003-0775: If saned expects strings, it mallocs the memory
necessary to store the complete string after it receives the size of the
string. If the connection was dropped before transmitting the size,
malloc will reserve an arbitrary size of memory. Depending on that size
and the amount of memory available either malloc fails (->saned quits
nicely) or a huge amount of memory is allocated. Swapping and OOM
measures may occur depending on the kernel.
-
CAN-2003-0776: saned doesn't check the validity of the RPC numbers
it gets before getting the parameters.
-
CAN-2003-0777: If debug messages are enabled and a connection is
dropped, non-null-terminated strings may be printed and segmentation
faults may occur.
-
CAN-2003-0778: It's possible to allocate an arbitrary amount of
memory on the server running saned even if the connection isn't dropped.
At the moment this can not easily be fixed according to the author.
Better limit the total amount of memory saned may use (ulimit).
