Updated python packages fix predictable temporary file

Advisory:	RHSA-2002:202-35
Type:	Security Advisory
Severity:	N/A
Issued on:	2002-09-12
Last updated on:	2003-06-30
Affected Products:	Red Hat Linux 6.2 Red Hat Linux 7.0 Red Hat Linux 7.1 Red Hat Linux 7.1 for iSeries Red Hat Linux 7.1 for pSeries Red Hat Linux 7.2 Red Hat Linux 7.3
OVAL:	N/A
CVEs (cve.mitre.org):	CVE-2002-1119

Details

An insecure use of a temporary file has been found in Python. This erratum
provides updated Python packages.

[updated Feb 12 2003]
Updated packages for Red Hat Linux 7.3 are available that fix a binary
incompatibility change in the original erratum packages that affected
redhat-config-users, and to add back the missing python-tools package.

[Updated 16 April 2003]
Added packages for Red Hat Linux on IBM iSeries and pSeries systems.

Python is an interpreted, interactive, object-oriented programming
language.

Zack Weinberg discovered that os._execvpe from os.py in Python 2.2.1 and
earlier creates temporary files with predictable names. This could allow
local users to execute arbitrary code via a symlink attack.

All users should upgrade to these errata packages, which contain a patch to
python 1.5.2 and are not vulnerable to this issue. Please note that for
Red Hat Linux 7.3 we have updated the python2 packages from version 2.2 to
version 2.2.2. Red Hat Linux 8.0 shipped a version of Python that already
contained a fix for this issue and is therefore not vulnerable to this issue.

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.
