___________________________________________________________________________
A security hole was discovered in the package mentioned above.
Please update the package in your installation as soon as possible.
___________________________________________________________________________
1. Problem Summary
Squid has a flaw in the code to handle FTP PUT commands: when a mkdir-only
request was done squid would detect an internal error and exit.
Squid script cannot use the restart command. Because when stop command
isn't finished, start command is started.
2. Impact
Vulnerable.
3. Solution
Update the package from our ftp server by running the following command:
rpm -Uvh ftp://ftp.turbolinux.com/pub/updates/6.0/security/
Where is the following:
squid-2.4.STABLE2-3.i386.rpm
The source RPM can be downloaded here:
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/ squid-2.4.STABLE2-3.src.rpm
**Note: You must rebuild and install the RPM if you choose to download
and install the SRPM. Simply installing the SRPM alone WILL NOT CLOSE
THE SECURITY HOLE.
Please verify the MD5 checksums of the updates before you install:
MD5 sum Package Name
