  - Provided an attacker has privileges to create symlinks
    on the file system, it may be possible to partially read

  - 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)

"Several vulnerabilities have been discovered in mapserver, a CGI-based
web framework to publish spatial data and interactive mapping
applications. The Common Vulnerabilities and Exposures project
identifies the following problems :

  - CVE-2009-0843
    Missing input validation on a user-supplied map
    queryfile name can be used by an attacker to check for
    the existence of a specific file by using the queryfile
    GET parameter and checking for differences in error
    messages.

  - CVE-2009-0842
    A lack of file type verification when parsing a map file
    can lead to partial disclosure of content from arbitrary
    files through parser error messages.

  - CVE-2009-0841
    Due to missing input validation when saving map files
    under certain conditions it is possible to perform
    directory traversal attacks and to create arbitrary
    files. NOTE: Unless the attacker is able to create
    directories in the image path or there is already a
    readable directory this doesn't affect installations on
    Linux as the fopen() syscall will fail in case a sub
    path is not readable.

  - CVE-2009-0839
    It was discovered that mapserver is vulnerable to a
    stack-based buffer overflow when processing certain GET
    parameters. An attacker can use this to execute
    arbitrary code on the server via crafted id parameters.

  - CVE-2009-0840
    An integer overflow leading to a heap-based buffer
    overflow when processing the Content-Length header of an
    HTTP request can be used by an attacker to execute
    arbitrary code via crafted POST requests containing
    negative Content-Length values.

  - CVE-2009-2281
    An integer overflow when processing HTTP requests can
    lead to a heap-based buffer overflow. An attacker can
    use this to execute arbitrary code either via crafted
    Content-Length values or large HTTP request. This is
    partly because of an incomplete fix for CVE-2009-0840."
