   Apple Mac OS X is affected by multiple vulnerabilities

   Original release date: May 16, 2005
   Last revised: --
   Source: US-CERT

Systems Affected

   Mac OS X version 10.3.9 (Panther) and Mac OS X Server version 10.3.9


   Apple has released Security Update 2005-005 to address multiple
   vulnerabilities affecting Mac OS X and Mac OS X Server. The most
   serious of these vulnerabilities may allow a remote attacker to
   execute arbitrary code. Impacts of other vulnerabilities addressed by
   the update include disclosure of information and denial of service.

I. Description

   Apple Security Update 2005-005 resolves a number of vulnerabilities
   affecting Mac OS X and OS X Server. Further details are available in
   the following Vulnerability Notes:

   VU#356070 - Apple Terminal fails to properly sanitize input for
   x-man-page URI

    Apple Terminal on Mac OS X fails to sanitize x-man-page URIs, allowing
    a remote attacker to execute arbitrary commands.

   VU#882750 - libXpm image library vulnerable to buffer overflow

    libXpm image parsing code contains a buffer-overflow vulnerability
    that may allow a remote attacker execute arbitrary code or cause a
    denial-of-service condition.

   VU#125598 - LibTIFF vulnerable to integer overflow via corrupted
   directory entry count

    An integer overflow in LibTIFF may allow a remote attacker to execute
    arbitrary code.

   VU#539110 - LibTIFF vulnerable to integer overflow in the
   TIFFFetchStrip() routine

    An integer overflow in LibTIFF may allow a remote attacker to execute
    arbitrary code.

   VU#537878 - libXpm library contains multiple integer overflow

    libXpm contains multiple integer-overflow vulnerabilities that may
    allow a remote attacker execute arbitrary code or cause a
    denial-of-service condition.

   VU#331694 - Apple Mac OS X chpass/chfn/chsh utilities do not properly
   validate external programs

    Mac OS X Directory Service utilities do not properly validate code
    paths to external programs, potentially allowing a local attacker to
    execute arbitrary code.

   VU#582934 - Apple Mac OS X Foundation framework vulnerable to buffer
   overflow via incorrect handling of an environmental variable

    A buffer overflow in Mac OS X's Foundation Framework's processing of
    environment variables may lead to elevated privileges.

   VU#706838 - Apple Mac OS X vulnerable to buffer overflow via vpnd

    Apple Mac OS X contains a buffer overflow in vpnd that could allow a
    local, authenticated attacker to execute arbitrary code with root

   VU#258390 - Apple Mac OS X with Bluetooth enabled may allow file
   exchange without prompting users

    Apple Mac OS X with Bluetooth support may unintentionally allow files
    to be exchanged with other systems by default.

   VU#354486 - Apple Mac OS X Server Netinfo Setup Tool fails to validate
   command line parameters

    Apple Mac OS X Server NeST tool contains a vulnerability in the
    processing of command line arguments that could allow a local attacker
    to execute arbitrary code.
   Please note that Apple Security Update 2005-005 addresses additional
   vulnerabilities not described above. As further information becomes
   available, we will publish individual Vulnerability Notes.
