rh-postgresql security update

Synopsis

rh-postgresql security update

Type/Severity

Security Advisory: Low

Topic

Updated rh-postgresql packages that fix various bugs are now available.

Description

PostgreSQL is an advanced Object-Relational database management system
(DBMS) that supports almost all SQL constructs (including transactions,
subselects, and user-defined types and functions).

Trustix has identified improper temporary file usage in the
make_oidjoins_check script. It is possible that an attacker could
overwrite arbitrary file contents as the user running the
make_oidjoins_check script. This script has been removed from the RPM file
since it has no use to ordinary users. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0977 to
this issue.

Additionally, the following non-security issues have been addressed:

• Fixed a low probability risk for loss of recently committed transactions.
  
• Fixed a low probability risk for loss of older data due to failure to
  update transaction status.
  
• A lock file problem that sometimes prevented automatic restart after a
  system crash has been fixed.
  

All users of rh-postgresql should upgrade to these updated packages, which
resolve these issues.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains
the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

If up2date fails to connect to Red Hat Network due to SSL
Certificate Errors, you need to install a version of the
up2date client with an updated certificate. The latest version of
up2date is available from the Red Hat FTP site and may also be
downloaded directly from the RHN website:
