S-263: mapserver Vulnerabilities

[Debian Security Advisory DSA-1539-1]

April 10, 2008 15:00 GMT


PROBLEM:	There are two vulnerabilities in mapserver, a development environment for spatial and mapping applications: 1) lack on input sanitizing and output escaping in the CGI mapserver's template handling and error reporting routines; and 2) missing bounds checking in mapserver's template handling.
PLATFORM:	Debian GNU/Linux 4.0 (etch)
DAMAGE:	Cross-site scripting or execution of arbitrary code.
SOLUTION:	Upgrade to the appropriate version.

VULNERABILITY ASSESSMENT:	The risk is LOW. Could lead to cross-site scripting or stack-based buffer overrun vulnerability, allowing a remote attacker to execute arbitrary code with the privileges of the CGI or httpd user.

CVSS 2 BASE SCORE: TEMPORAL SCORE: VECTOR:	6.4 5.0 (AV:N/AC:L/Au:N/C:P/I:P/A:N/E:POC/RL:OF/RC:C)

Security database references:

In Mitre's CVE dictionary: CVE-2007-4542, CVE-2007-4629.

More information:

Chris Schmidt and Daniel Morissette discovered two vulnerabilities in mapserver, a development environment for spatial and mapping applications. The Common Vulnerabilities and Exposures project identifies the following two problems:

CVE-2007-4542
Lack of input sanitizing and output escaping in the CGI mapserver's template handling and error reporting routines leads to cross-site scripting vulnerabilities.
CVE-2007-4629
Missing bounds checking in mapserver's template handling leads to a stack-based buffer overrun vulnerability, allowing a remote attacker to execute arbitrary code with the privileges of the CGI or httpd user.

For the stable distribution (etch), these problems have been fixed in version 4.10.0-5.1+etch2.

For the unstable distribution (sid), these problems have been fixed in version 4.10.3-1.

We recommend that you upgrade your mapserver (4.10.0-5.1+etch2) package.

Fixed in:

Debian GNU/Linux 4.0 (etch)
