mapserver - several

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.
