Summary
Red Hat Security Advisory: : : : New rsync packages fix remote security vulnerability

Notes

Topic
Updated rsync packages are now available that fix a heap overflow in the Rsync server.
Details
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 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.

Only those\nRPMs which are currently installed will be updated.  Those RPMs which are\nnot installed but included in the list will not be updated.  Note that you\ncan also use wildcards (*.rpm) if your current directory *only* contains the\ndesired RPMs.\n\nPlease note that this update is also available via Red Hat Network.  Many\npeople find this an easier way to apply updates.  To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.\n\nIf up2date fails to connect to Red Hat Network due to SSL Certificate \nErrors, you need to install a version of the up2date client with an updated \ncertificate.  The latest version of up2date is available from the Red Hat \nFTP site and may also be downloaded directly from the RHN website:\n\nhttps://rhn.redhat.com/help/latest-up2date.px",
