CONECTIVA LINUX SECURITY ANNOUNCEMENT

PACKAGE   : kde
SUMMARY   : Fix for multiple security vulnerabilities
DATE      : 2004-09-13 11:35:00
ID        : CLA-2004:864

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.

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.
