How to determine if you are affected:
For products on Windows:

   default, the file is located in the 
   “C:\Program Files\CA\SharedComponents\ScanEngine” directory(*).
2. Right click on the file and select Properties.
3. Select the Version tab.
4. If the file version is earlier than indicated in the table 
   below, the installation is vulnerable.

File Name    File Version
arclib.dll   7.3.0.9

*For eTrust Intrusion Detection 2.0 the file is located in 
“Program Files\eTrust\Intrusion Detection\Common”, and for eTrust 
Intrusion Detection 3.0 and 3.0 sp1, the file is located in 
“Program Files\CA\Intrusion Detection\Common”.

For CA Anti-Virus r8.1 on non-Windows:
Use the compver utility provided on the CD to determine the 
version of arclib.dll. The same version information above applies.
