Red Hat alert RHSA-2003:399-01 (rsync)
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: New rsync packages fix remote security vulnerability Advisory ID: RHSA-2003:399-01 Issue date: 2003-12-04 Updated on: 2003-12-04 Product: Red Hat Enterprise Linux Keywords: rsync heap overflow Cross references: Obsoletes: CVE Names: CAN-2003-0962 - --------------------------------------------------------------------- 1. Topic: Updated rsync packages are now available that fix a heap overflow in the Rsync server. 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 Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, 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: rsync is a program for sychronizing files over the network. A heap overflow bug exists in rsync versions prior to 2.5.7. On machines where the rsync server has been enabled, a remote attacker could use this flaw to execute arbitrary code as an unprivileged user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0962 to this issue. All users should upgrade to these erratum packages containing version 2.5.7 of rsync, which is not vulnerable to this issue. NOTE: The rsync server is disabled (off) by default in Red Hat Enterprise Linux. To check if the rsync server has been enabled (on), run the following command: /sbin/chkconfig --list rsync If the rsync server has been enabled but is not required, it can be disabled by running the following command as root: /sbin/chkconfig rsync off Red Hat would like to thank the rsync team for their rapid response and quick fix for this issue. 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://rhn.redhat.com/help/latest-up2date.pxt 5.
