Red Hat Advisory: RHSA-2005:495-01 Low: Security Concern for rsh

Updated rsh packages that fix a theoretical security issue are now available. This update has been rated as having low security impact by the Red Hat Security Response Team. - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Low: rsh security update Advisory ID: RHSA-2005:495-01 Advisory URL: https://access.redhat.com/errata/RHSA-2005:495.html Issue date: 2005-06-13 Updated on: 2005-06-13 Product: Red Hat Enterprise Linux CVE Names: CAN-2004-0175 - ---------------------------------------------------------------------1. Summary: Updated rsh packages that fix a theoretical security issue are now available. This update has been rated as having low security impact by the Red Hat Security Response Team 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386 3. Problem description: The rsh package contains a set of programs that allow users to run commands on remote machines, login to other machines, and copy files between machines, using the rsh, rlogin, and rcp commands. All three of these commands use rhosts-style authentication. The rcp protocol allows a server to instruct a client to write to arbitrary files outside of the current directory. This could potentially cause a security issue if a user uses rcp to copy files from a malicious server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0175 to this issue. All users of rsh should upgrade to these updated packages, which resolve these issues. 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. If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website: https://access.redhat.com 5. Bug IDs fixed (http://bugzilla.redhat.com/): 158916 - CAN-2004-0175 malicious rsh server can cause rcp to write to arbitrary files 6.

Red Hat Enterprise Linux 3: RHSA-2005:074-01 Low: Rsh Issue

Updated rsh packages that fix various bugs and a theoretical security issue are now available. This update has been rated as having low security impact by the Red Hat Security Response Team. - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Low: rsh security update Advisory ID: RHSA-2005:074-01 Advisory URL: https://access.redhat.com/errata/RHSA-2005:074.html Issue date: 2005-05-18 Updated on: 2005-05-18 Product: Red Hat Enterprise Linux CVE Names: CAN-2004-0175 - ---------------------------------------------------------------------1. Summary: Updated rsh packages that fix various bugs and a theoretical security issue are now available. This update has been rated as having low security impact by the Red Hat Security Response Team 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 3. Problem description: The rsh package contains a set of programs that allow users to run commands on remote machines, login to other machines, and copy files between machines, using the rsh, rlogin, and rcp commands. All three of these commands use rhosts-style authentication. The rcp protocol allows a server to instruct a client to write to arbitrary files outside of the current directory. This could potentially cause a security issue if a user uses rcp to copy files from a malicious server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0175 to this issue. These updated packages also address the following bugs: The rexec command failed with "Invalid Argument", because the code used sigaction() as an unsupported signal. The rlogind server reported "SIGCHLD set to SIG_IGN but callswait()" message to the system log because the original BSD code was ported incorrectly to linux. The rexecd server did not function on systems where client hostnames were not in the DNS service, because server code called gethostbyaddr() for each new connection. The rcp command incorrectly used the "errno" variable and produced erroneous error messages. The rexecd command ignored settings in the /etc/security/limits file, because the PAM session was incorrectly initialized. The rexec command prompted for username and password regardless of the ~/.netrc configuration file contents. This updated package contains a patch that no longer skips the ~/.netrc file. All users of rsh should upgrade to these updated packages, which resolve these issues. 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. If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website: https://access.redhat.com 5.
