A vulnerability was discovered in the rmtree() function in File::Path.pm.
While a process running as root (or another user) was busy deleting a
directory tree, a different user could exploit a race condition to create
setuid binaries in this directory tree, provided that he already had write
permissions in any subdirectory of that tree.
An integer overflow flaw was found in libXPM, which is used by some
applications for loading of XPM images. An attacker could create a malicious
XPM file that would execute arbitrary code via a negative bitmap_unit value if
opened by a victim using an application linked to the vulnerable library.

Computer Associates International, Inc.'s (CA) eTrust Intrusion Detection 3.0 is a complete session security
solution for network protection, network session monitoring and Internet web filtering.
A vulnerability exists due to insufficient checking on values passed to Microsoft's Crypto API function
CPImportKey. The CPImportKey function determines certain buffer allocation sizes from data supplied in the
data blob passed to CPImportKey and may be manipulated to cause the allocation of large buffers if wrapper
functions do not validate the data passed to the Crypto API before calling CPImportKey.
In cases which CPImportKey receives a size value which exceeds the mapped memory size,
an exception is generated and the memory is never freed.
This is a Denial-of-Service.
For eTrust Intrusion Detection 3.0 a new download is available.

Certain release trains of Cisco Internetwork Operating System (IOS), when configured to use the IOS Secure Shell
(SSH) server in combination with Terminal Access Controller Access Control System Plus (TACACS+) as a means to
perform remote management tasks on IOS devices, may contain two vulnerabilities that can potentially cause IOS
devices to exhaust resources and reload. Repeated exploitation of these vulnerabilities can result in a
Denial-of-Service (DoS) condition.
Use of SSH with Remote Authentication Dial In User Service (RADIUS) is not affected by these vulnerabilities.
Cisco IOS Software release trains 12.2T, 12.3 and 12.3T may contain vulnerabilities in processing certain
Internet Key Exchange (IKE) Xauth messages when configured to be an Easy VPN Server.
Successful exploitation of these vulnerabilities may permit an unauthorized user to complete authentication
and potentially access network resources.
Cisco has made free software available to address these vulnerabilities for all affected customers.

Turbolinux has published patches for the packages listed above. Some of the vulnerabilities are critical,
so it's recommended to install the updates.

Buffer overflow vulnerabilities occur in internal parsing components and built-in functions that are
accessible to all authenticated Sybase users.
They allow an attacker with no special permission to take advantage of these flaws and no mechanism exists
to prevent a user from executing the vulnerable code.
An unauthenticated Sybase User could trigger a buffer overflow and gain full control of the database server.
Due to a buffer overflow, at least a Denial-of-Service is possible.
It's strongly recommended to install the latest patches published by Sybase.

In phpMyAdmin 2.6.1 and prior the convcharset parameter isn't correctly set,
so there is a Cross-Site Scripting vulnerability (XSS).
It's recommended to ugrade to phpMyAdmin 2.6.2-rc1 or newer.

A remote attacker may gain root access to a system configured as a NIS client.
Note that it's also possible for a local attacker to exploit this vulnerability.
Versions of AIX prior to AIX 5.3 are not affected by this issue.
An official patch is available.

Windows Server 2003 has two denial of service vulnerabilties by which
authenticated local users, and in particular Terminal Services users
can crash the server.
A Terminal Services user can cause the system to crash.
This may be exploited by opening a Microsoft Word attachment in Outlook
then printing it to a network printer.
When a SMB browser announcement frame is wrongly processed by the
SMB redirector, it may attempt to execute code that is paged out
and unavailable, resulting in a "STOP 0x000000D1" blue screen error.
A local user can exploit this for example by retrieving large files
from a network share when the system is under heavy load.
These vulnerabilities are fixed in Windows Server 2003 Service Pack 1.

SGI has released Security Update #32 for SGI Advanced Linux Environment 3.
These updates fix security related problems in
imagemagick, ipsec-tools, and mozilla.
It's recommended to install this update.

The Linux kernel is the core component of the Linux system.
A problem was found within the Bluetooth kernel stack which can be used
by a local attacker to gain root access or crash the machine.
Fixed kernel packages are available now.
|
|
|
The sendfile(2) system call allows a server application to transmit the
contents of a file over a network connection without first copying it
to application memory.
If the file being transmitted is truncated after the transfer has
started but before it completes, sendfile(2) will transfer the contents
of more or less random portions of kernel memory in lieu of the
missing part of the file.
Unprivileged users on amd64 systems can gain direct access to some
hardware, allowing for denial of service, disclosure of sensitive
information, or possible privilege escalation.
Patches are available now.

A bug was found in the way gdk-pixbuf processes BMP images. It is possible
that a specially crafted BMP image could cause a denial of service attack
on applications linked against gdk-pixbuf.
cURL is a tool for getting files from FTP, HTTP, Gopher, Telnet, and
Dict servers, using any of the supported protocols.
Multiple buffer overflow bugs were found in the way curl processes base64
encoded replies. If a victim can be tricked into visiting a URL with curl,
a malicious web server could execute arbitrary code on a victim's machine.
Updated packages solve these problems.

Several vulnerabilities were found in remstats, the remote statistics system.
When processing uptime data on the unix-server a temporary file is
opened in an insecure fashion which could be used for a symlink
attack to create or overwrite arbitrary files with the permissions
of the remstats user.
The remoteping service can be exploited to execute arbitrary
commands due to missing input sanitising.
Several denial of service conditions have been discovered in wu-ftpd,
the popular FTP daemon.
A denial of service condition in wu-ftpd can be exploited by a remote user
and cause the server to slow down the server by resource exhaustion.
/bin/ls may be called from within wu-ftpd in a way that will result in
large memory consumption and hence slow down the server.
Fixed packages are available now.

|
A vulnerability within the Adobe Reader and Acrobat web control has been
identified. Under certain circumstances, if the Internet Explorer ActiveX
control is directly invoked by a web page, it is possible to discover the
existence of local files by monitoring the behavior of certain methods.
Fixed versions are available now.
|
|
|
A buffer overflow bug has been found in the way that grip handles data returned by CDDB servers.
If a user is connected to a malicious CDDB server, an attacker might execute arbitrary
code on the user's machine. An updated package addresses this issue.
|
|
|
TeTeX is an implementation of TeX for Linux or UNIX systems.
A number of security flaws have been found affecting libraries used internally within teTeX.
An attacker who has the ability to trick a user into processing a malicious file with teTeX could cause
teTeX to crash or possibly execute arbitrary code.
Additionally, a number of security related bugs concerning teTeX have been found in Xpdf and libtiff.
The gtk2 package contains the GIMP ToolKit (GTK+), a library for creating graphical user interfaces for the X Window System.
A bug has been found in the way gtk2 processes BMP images.
It's possible that a specially crafted BMP image could cause a Denial-of-Service attack on applications linked against gtk2.
Additionally, a double free vulnerability has been found.
Updated packages solve these problems.

Several vulnerabilities have been discovered in ImageMagick, a commonly used image manipulation library.
These problems can be exploited by a carefully crafted graphic image.
A format string vulnerability in the filename handling code might allow attackers to cause a Denial-of-Service
and possibly execute arbitrary code of attacker's choice.
A Denial-of-Service might occur due to in invalid tag in a TIFF image.
Additionally, the TIFF decoder is vulnerable to accessing memory out of bounds which will result in a
segmentation fault.
Finally, a buffer overflow in the SGI parser allows a remote attacker to execute arbitrary code via a specially
crafted SGI image file.
For most Linux a fixed package is available now.

Several vulnerabilities were found in PHP 4 and PHP 5.
Two vulnerability in the getimagesize() PHP routine could allow
unauthenticated remote attackers to consume 100% CPU resources on
vulnerable systems.
A vulnerability in swf_openfile() bypasses safe mode restrictions.
In conjunction with application vulnerabilities this can potentially
allow overwriting arbitrary files.
unserialize() corrupts floating point values in non-English locales.
Patches are available now.

|
A cross-site scripting vulnerability was discovered in ht://dig.
A buffer overflow was discovered in the way libexif parses EXIF tags. An
attacker could exploit this by creating a special EXIF image file which could
cause image viewers linked against libexif to crash.
Fixed packages are available now.
|
|
|
The racoon IKE daemon, contained in package ipsec-tools, can be crashed from
remote by sending a special crafted ISAKMP packet.
Fixed packages are available now.
