CVE-2006-5664
|

Description:
Some vulnerabilities have been reported in various Informix Products, which can be exploited by malicious, local users to perform certain actions with escalated privileges.
1) Insecure file permissions of the installation scripts of the applications can be exploited by unprivileged users to insert code, which will be executed during installation.
2) An error exists due to temporary files being created insecurely in "/tmp" during the installation process. This can be exploited via symlink attacks to create or overwrite arbitrary files with privileges of the user running the installation program.
The following products are affected:
* IBM Informix Dynamic Server version 10.00
* IBM Informix Client SDK version 2.90
* IBM Informix Connect version 2.90
Solution:
Grant only trusted users access to affected systems and use the "-log" option when performing the installation to create the temporary files in a secure directory.
The vulnerabilities will reportedly be fixed in the following versions:
-- IBM Informix Dynamic Server --
Solaris Opteron, Linux zSeries: Version 10.00.xC5R1
All others: Version 10.00.xC6
-- IBM Informix CSDK --
Solaris Opteron, Linux zSeries: Version 2.90.xC4R1
All others: Version 2.90.xC7
-- IBM Informix Connect --
Solaris Opteron, Linux zSeries: Version 2.90.xC4R1
All others: Version 2.90.xC7
