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

CVE-2003-0962

Heap-based buffer overflow in rsync before 2.5.7, when running in server mode, allows remote attackers to execute arbitrary code and possibly escape the chroot jail.

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",

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
