PLATFORM: Debian GNU/Linux 4.0 (etch) DAMAGE: Cross-site scripting or execution of arbitrary code. SOLUTION: Upgrade to the appropriate version. ______________________________________________________________________________ VULNERABILITY The risk is LOW. Could lead to cross-site scripting or ASSESSMENT: 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: 6.4 TEMPORAL SCORE: 5.0 VECTOR: (AV:N/AC:L/Au:N/C:P/I:P/A:N/E:POC/RL:OF/RC:C) ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/s-263.shtml ORIGINAL BULLETIN: http://www.debian.org/security/2008/dsa-1539 CVE: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CVE-2007-4542 CVE-2007-4629 ______________________________________________________________________________ [***** Start Debian Security Advisory DSA-1539-1 *****] Debian Security Advisory DSA-1539-1 mapserver -- several vulnerabilities Date Reported: 04 Apr 2008 Affected Packages: mapserver Vulnerable: Yes 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) Source: http://security.debian.org/pool/updates/main/m/mapserver/mapserver_4.10.0-5.1+etch2.dsc
