Posted by Team   
Mandrake WireX discovered a potential temporary file race condition in the way that squid sends out email messages notifying the administrator about updating the program.


                Linux-Mandrake Security Update Advisory

Package name:           squid
Date:                   January 10th, 2001
Advisory ID:            MDKSA-2001:003

Affected versions:      6.0, 6.1, 7.0, 7.1, 7.2

Problem Description:

 WireX discovered a potential temporary file race condition in the way
 that squid sends out email messages notifying the administrator about
 updating the program.  Usually this will only happen if you are running
 a development version of squid or if the clock on your system is
 incorrect.  This problem has been corrected in the latest stable and
 development versions of squid.

Please verify the update prior to upgrading to ensure the integrity of
the downloaded package.  You can do this with the command:
  rpm --checksig package.rpm
You can get the GPG public key of the Linux-Mandrake Security Team at
If you use MandrakeUpdate, the verification of md5 checksum and GPG
signature is performed automatically for you.
