    Debian: 'rsync' Remote command execution

    Date 25 Jan 2002
    Posted By LinuxSecurity Advisories
    There exist several signedness bugs within the rsync program which allow remote attackers to write 0-bytes to almost arbitrary stack-locations, therefore being able to control the programflow and obtaining a shell remotely.

    Package        : rsync
    Problem type   : remote exploit
    Debian-specific: no
    Sebastian Krahmer found several places in rsync (a popular tool to
    synchronise files between machines) where signed and unsigned numbers
    were mixed which resulted in insecure code. This could be abused by
    remote users to write 0-bytes in rsync's memory and trick rsync into
    executing arbitrary code.
    This has been fixed in version 2.3.2-1.3 and we recommend you upgrade
    your rsync package immediately.
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
