DESCRIPTION
KDE[1] is a very popular graphical desktop environment available for
GNU/Linux and other operating systems.
This announcement fixes the following vulnerabilities:
1. Use of predictable directory names (CAN-2004-0689[2])
As discovered by Andrew Tuitt, KDE's usage of predictable directory
names could be used by a local attacker to cause a denial of service,
even allowing file overwritting.
2. Use of insecure temporary files (CAN-2004-0690[3])
KDE's DCOPServer created temporary files in an insecure manner. Since
this temporary files are used for authentication related purposes
this could potentially allow a local attacker to compromise the
account of any user which runs a KDE application.
3. Cookie injection in Konqueror (CAN-2004-0746[4])
WESTPOINT internet reconnaissance services alerted the KDE security
team that the KDE web browser Konqueror allowed websites to set
cookies for certain country specific secondary top level domains and
that it could be used as a part of a session fixation attack.
4. Frame injection in Konqueror (CAN-2004-0721[5])
A frame injection vulnerability was found by Gary McKay first on a
Mozilla browser but it also affected KDE's browser, Konqueror. A
malicious website could use this to load arbitrary content in an
arbitrary frame in any other browser window.
SOLUTION
It is recommended that all users of the KDE desktop, including those
who use other desktop and only use certain KDE components such as
Konqueror, upgrade their KDE packages.
IMPORTANT: in order to close the vulnerbilities, all KDE applications
have to be restarted.

CONECTIVA LINUX SECURITY ANNOUNCEMENT

PACKAGE : zlib
SUMMARY : Fix for denial of service vulnerabilities

DESCRIPTION
"zlib"[1] is a compression library used by several programs.
Due to a Debian bug report[2], a denial of service vulnerability[2]
was discovered in the zlib compression library versions 1.2.x, in the
inflate() and inflateBack() functions. An attacker could exploit
this vulnerability to launch a denial of service attack on any
application using the zlib library. Older versions of zlib are not
affected.
SOLUTION
It is recommended that all Conectiva Linux users upgrade their
packages.
IMPORTANT: all applications linked against zlib must be restarted
after the upgrade in order to close the vulnerabilities.
