--------------------------------------------------------------------- Fedora Legacy Update Advisory
Synopsis: Updated rp-pppoe package fixes security issue Advisory ID: FLSA:152794 Issue date: 2005-11-14 Product: Red Hat Linux, Fedora Core Keywords: Bugfix CVE Names: CVE-2004-0564 ---------------------------------------------------------------------
--------------------------------------------------------------------- 1. Topic:
An updated rp-pppoe package that fixes a security vulnerability is now available.
The rp-pppoe package is a PPP over Ethernet client (for xDSL support).
2. Relevant releases/architectures:
Red Hat Linux 7.3 - i386 Red Hat Linux 9 - i386 Fedora Core 1 - i386
3. Problem description:
Max Vozeler discovered a vulnerability in pppoe, the PPP over Ethernet driver from Roaring Penguin. When the program is running setuid root (which is not the case in a default Red Hat Linux or Fedora Core installation), an attacker could overwrite any file on the file system. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0564 to this issue.
All users of rp-pppoe should upgrade to this updated package, which resolves this issue.
4. 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 yum and apt. Many people find this an easier way to apply updates. To use yum issue:
yum update
or to use apt:
apt-get update; apt-get upgrade
This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www.fedoralegacy.org/docs for directions on how to configure yum and apt-get.
5. Bug IDs fixed:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=152794
6. RPMs required:
Red Hat Linux 7.3: SRPM: rp-pppoe-3.3-10.legacy.src.rpm
i386: rp-pppoe-3.3-10.legacy.i386.rpm
Red Hat Linux 9:
SRPM: rp-pppoe-3.5-2.2.legacy.src.rpm
i386: rp-pppoe-3.5-2.2.legacy.i386.rpm
Fedora Core 1:
