Summary:

rsync could be made to crash or run programs if it received
specially crafted network traffic.

Software Description:

Original advisory details:

  Danilo Ramos discovered that rsync incorrectly handled memory when
  performing certain zlib deflating operations. An attacker could use this
  issue to cause rsync to crash, resulting in a denial of service, or
  possibly execute arbitrary code.

package versions:
