Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated wu-ftpd packages are available
Advisory ID: RHSA-2001:157-06
Issue date: 2001-11-20
Updated on: 2001-11-26
Product: Red Hat Linux
Keywords: wu-ftpd buffer overrun glob ftpglob
Cross references:
Obsoletes: RHSA-2000:039
- ---------------------------------------------------------------------
1. Topic:
Updated wu-ftpd packages are available to fix an overflowable buffer.
2. Relevant releases/architectures:
Red Hat Linux 6.2 - alpha, i386, sparc
Red Hat Linux 7.0 - alpha, i386
Red Hat Linux 7.1 - alpha, i386, ia64
Red Hat Linux 7.2 - i386
3. Problem description:
An overflowable buffer exists in earlier versions of wu-ftpd.
An attacker could gain access to the machine by sending malicious
commands.
It is recommended that all users of wu-ftpd upgrade to the lastest
version.
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 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.
