"According to its version, the installation of BrightStor ARCserve
Backup on the remote host is affected by multiple issues :

  - A vulnerability in 'caloggerd' could allow an 
    unauthenticated attacker to append data to arbitrary 
    files on the server using log messages with directory
    traversal sequences, which could lead to a system
    compromise.

  - Insufficient boundary checks in multiple 'xdr' 
    functions could allow an unauthorized attacker to 
    execute arbitrary code with SYSTEM level privileges 
    or cause a denial of service condition.");
