  • FixedRed Hat Linux 7.1redhat_csaf

    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. Also note that users of vipw may want to run (as root): chmod 0400 /etc/shadow to ensure that the file has the correct permissions.

  • RHSA-2001:095Red Hat Security Advisory: : New util-linux packages available to fix vipw permissions problems2001-07-16csaf · redhat_csafUS

    New util-linux packages are available for Red Hat Linux 7.1. These packages fix a problem where vipw would leave the /etc/shadow file world-readable after editing it. It is recommended that all users update to the fixed packages. Also, if you have used vipw on Red Hat Linux 7.1 before, make sure to run (as root): chmod 0400 /etc/shadow

  • RHSA-2001:132Red Hat Security Advisory: : New util-linux packages available to fix /bin/login pam problem2001-10-16csaf · redhat_csafUS

    New util-linux packages are available that fix a problem with /bin/login's PAM implementation. This could, in some non-default setups, cause users to receive credentials of other users. It is recommended that all users update to the fixed packages. 2001-10-22: Packages are now available for Red Hat Linux 7.2. Notably, these packages also fix the problem noted in RHSA-2001:095-04 (vipw incorrectly setting permissions on some files) - this bug was accidentally reintroduced in Red Hat Linux 7.2.
