Package        : zope-cmfplone
Vulnerability  : missing input sanitising
Problem-Type   : remote
Debian-specific: no
CVE ID         : CVE-2007-5741
Debian Bug     : 449523

The Plone developers discovered that their hotfix, released as DSA 1405,
introduced two regressions. This update corrects these flaws. For
completeness, the original advisory text below:

It was discovered that Plone, a web content management system, allows
remote attackers to execute arbitrary code via specially crafted web
browser cookies.

The oldstable distribution (sarge) is not affected by this problem.

For the stable distribution (etch) this problem has been fixed in
version 2.5.1-4etch3.

For the unstable distribution (sid) this problem has been fixed in
version 2.5.2-3.

We recommend that you upgrade your zope-cmfplone package.
