More information:

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-2011-2703

    Several instances of insufficient escaping of user input, leading to SQL injection attacks via OGC filter encoding (in WMS, WFS, and SOS filters).

  • CVE-2011-2704

    Missing length checks in the processing of OGC filter encoding that can lead to stack-based buffer overflows and the execution of arbitrary code.

For the oldstable distribution (lenny), these problems have been fixed in version 5.0.3-3+lenny7.

For the stable distribution (squeeze), these problems have been fixed in version 5.6.5-2+squeeze2.

For the testing (squeeze) and unstable (sid) distributions, these problems will be fixed soon.

We recommend that you upgrade your mapserver packages.
