RHSA-2004:004 - Security Advisory
Synopsis
cvs security update
Type/Severity
Security Advisory: Low
Topic
Updated cvs packages closing a vulnerability that could allow cvs to
attempt to create files and directories in the root file system are now
available.
Description
CVS is a version control system frequently used to manage source code
repositories.
A flaw was found in versions of CVS prior to 1.11.10 where a malformed
module request could cause the CVS server to attempt to create files or
directories at the root level of the file system. However, normal file
system permissions would prevent the creation of these misplaced
directories. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2003-0977 to this issue.
Users of CVS are advised to upgrade to these erratum packages, which
contain a patch correcting this issue.
For Red Hat Enterprise Linux 2.1, these updates also fix an off-by-one
overflow in the CVS PreservePermissions code. The PreservePermissions
feature is not used by default (and can only be used for local CVS). The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2002-0844 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.
