Originally issued: 28 February '02

---------------------------------------------------------------
The information in the following Security Bulletin should be acted
upon as soon as possible. Hewlett-Packard Company will not be liable
for any consequences to any customer resulting from the customer's
failure to fully implement instructions in this Security Bulletin
as soon as possible.
Because the vulnerability does not require a Hewlett-Packard
Secure OS 1.0 patch or re-packaging of the RPM affected by the
bulletin, the RPMs have not been produced or tested by Hewlett-Packard.
---------------------------------------------------------------
PROBLEM: Memory leak, URL parsing crash, and activation errors in
Squid package
PLATFORM: Any system running HP Secure OS software for Linux Release 1.0
DAMAGE: Resource issue due to memory leak. Possible denial of service
due to FTP URL parsing code. HTCP service is active even if
disabled in configuration file.
SOLUTION: Apply the appropriate RPMs (see section B below)
MANUAL ACTIONS: None
AVAILABILITY: The RPMs are available now.
CHANGE SUMMARY: ** Rev. 1 ** An updated RPM is available now.
---------------------------------------------------------------
A. Background
Squid is a high-performance proxy caching server. Various issues
have been found in Squid up to and including version 2.4.STABLE2.
The issues include:
- a memory leak in the SNMP code
- a crash on specially-formatted data in FTP URL parsing
- HTCP would still be active, even if it was disabled in the config
file
The updated pacakge contains Squid version 2.4.STABLE3. Squid
is not included in the default installation of HP Secure OS
Software for Linux Release 1.0.
** Rev. 1 **
>>> Additional squid security vulnerabilities were found, corrected
and updated in the squid RPM package previously made available
under Red Hat Security Advisory number RHSA-2002-029.
B. Fixing the problem
Hewlett-Packard Company recommends that customers who have installed
squid download the RPMs listed in the following Red Hat
Security Advisory:

To install the security bulletin RPMs, use the following sequence
of commands:
1. If you use the tripwire product, we recommend that you run a
a consistency check and fix any violations before installing
the security bulletin RPM.
tripwire --check --interactive
2. Install the bulletin RPM from the root account.
rpm -F <bulletin RPM name>
3. Update the tripwire database
tripwire --check --interactive
NOTE:
The rpm -q <package name> command can be used to determine if the
package is installed. Hewlett-Packard recommends applying the
security bulletin fixes to installed packages only. The -F option
to the RPM installer will only apply the fix if the package is
currently installed on the system. Dependent RPMs can be found by
using the "Find Latest RPMs" search facility at
http://www.redhat.com/apps/download. To find the latest dependent
RPM enter the RPM's name in the "By Keyword" box.
