    Sebastian Krahmer discovered that rsync, a fast remote file copy program,
    contains an off-by-one error which might allow remote attackers to execute
    arbitary code via long directory names.
    
    For the stable distribution (etch), this problem has been fixed in version
    2.6.9-2etch1.
    
    For the old stable distribution (sarge), this problem is not presnt.

    We recommend that you upgrade your rsync package.
