TITLE:
MapServer Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA34520

VERIFY ADVISORY:
https://secunia.com/advisories/34520/

DESCRIPTION:
Some vulnerabilities and a weakness have been reported in MapServer,
which can be exploited by malicious people to disclose potentially
sensitive information, bypass certain security restrictions, cause a
DoS (Denial of Service), and potentially to compromise a vulnerable
system.

1) A boundary error in the "mapserv" CGI program can be exploited to
cause a stack-based buffer overflow e.g. via a specially crafted map
file or potentially via specially crafted requests containing an
overly long string (128 bytes) passed via the "id" parameter.

Successful exploitation may allow execution of arbitrary code.

2) An indexing error exists when processing the "Content-Length"
header within the "mapserv" CGI program. This can be exploited to
cause an out-of-bounds array access via a specially crafted POST
request.

Successful exploitation requires a web server that does not sanitise
the "Content-Length" header.

3) Input passed to the "id" parameter to the "mapserv" CGI program is
not properly sanitised before being used. This can be exploited to
write files to arbitrary locations via directory traversal attacks.

4) An error in the "mapserv" CGI program in the processing of local
.map files can be exploited to disclose potentially sensitive
information in arbitrary .map files by specifying a full path via the
"map" parameter.

5)  An error in the "mapserv" CGI program in the processing of local
.map files can be exploited to disclose the existence of local files
via the "queryfile" parameter.

6) Boundary errors within the "msGenerateImages()" function in
maptemplate.c can potentially be exploited to cause stack-based
buffer overflows via a specially crafted map file.

The vulnerabilities and the weakness are reported in version prior to
5.2.2 and 4.10.4.

SOLUTION:
Update to version 5.2.2 or 4.10.4.
