Advisory ID: RHSA-2003:095-03
Issue date: 2003-03-17
Updated on: 2003-04-01
Product: Red Hat Linux
Keywords: smb
Cross references:
Obsoletes: RHSA-2002:266
CVE Names: CAN-2003-0085 CAN-2003-0086
---------------------------------------------------------------------
1. Topic:
Updated Samba packages are now available to fix security vulnerabilities
found during a code audit.
[Updated 24 March 2003]
Updated Samba packages for Red Hat Linux 6.2, 7, and 7.1 are now included.
These packages contain Samba version 2.0.10 with a backported security fix.
[Updated 1 April 2003]
Updated Samba packages for Red Hat Linux 9 are now included. Please note
that this issue only affects Red Hat Linux 9 boxed sets manufactured for
distribution within the United States. The part numbers, which can be
found on the bottom flap of the box, are RHF0120US and RHF0121US.
Copies of Red Hat Linux 9 obtained through other means (such as from Red
Hat Network, FTP, or international boxed sets) already contain the
packages referenced by this erratum, and are not vulnerable to this issue.
2. Relevant releases/architectures:
Red Hat Linux 6.2 - i386
Red Hat Linux 7.0 - i386
Red Hat Linux 7.1 - i386
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386
Red Hat Linux 9 - i386
3. Problem description:
Samba is a suite of utilities which provides file and printer sharing
services to SMB/CIFS clients.
Sebastian Krahmer discovered a security vulnerability present
in unpatched versions of Samba prior to 2.2.8. An anonymous user could
exploit the vulnerability to gain root access on the target machine.
Additionally, a race condition was discovered which could allow an attacker
to overwrite critical system files.
All users of Samba are advised to update to the packages listed in this
errata which correct these vulnerabilities.
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.
