"The remote host is running MapServer, an open source Internet map
server. The installed version of MapServer is affected by multiple
flaws :

  - By creating a map file with overly long IMAGEPATH and/or
    NAME attribute(s), it may be possible to trigger a
    stack-based buffer overflow. (CVE-2009-0839)

  - It may be possible to trigger a heap-based buffer
    overflow by sending a HTTP POST request with
    'CONTENT_LENGTH' attribute set to '-1'. (CVE-2009-0840)
    Note: According to some reports this issue might have
    been incorrectly fixed, see references for more info.

  - It may be possible to create arbitrary files by
    specifying file names to the 'id' parameter.
    (CVE-2009-0841)

  - Provided an attacker has privileges to create symlinks
    on the file system, it may be possible to partially read
    the contents of arbitrary files. (CVE-2009-0842)

  - Provided an attacker has knowledge of a valid map file,
    it may be possible to determine if an arbitrary file
    exists on the remote system. (CVE-2009-0843)

  - Sufficient boundary checks are not performed on 'id'
    parameter in mapserver.c. An attacker may exploit
    this issue to trigger a buffer overflow condition
    resulting in arbitrary code execution on the remote
    system. (CVE-2009-1176)

  - File maptemplate.c is affected by multiple stack-based
    overflow issues. (CVE-2009-1177)");
