USN-1604-1: MoinMoin vulnerabilities

Releases

• Ubuntu 12.04
• Ubuntu 11.10
• Ubuntu 11.04
• Ubuntu 10.04

Packages

• moin - Collaborative hypertext environment

Details

It was discovered that MoinMoin did not properly sanitize certain input,
resulting in a cross-site scripting (XSS) vulnerability. With cross-site
scripting vulnerabilities, if a user were tricked into viewing server
output during a crafted server request, a remote attacker could exploit
this to modify the contents, or steal confidential data, within the same
domain. (CVE-2011-1058)

It was discovered that MoinMoin incorrectly handled group names that
contain virtual group names such as "All", "Known" or "Trusted". This could
result in a remote user having incorrect permissions. (CVE-2012-4404)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.04

• python-moinmoin - 1.9.3-1ubuntu2.1

Ubuntu 11.10

• python-moinmoin - 1.9.3-1ubuntu1.11.10.1

Ubuntu 11.04

• python-moinmoin - 1.9.3-1ubuntu1.11.04.1

Ubuntu 10.04

• python-moinmoin - 1.9.2-2ubuntu3.2

In general, a standard system update will make all the necessary changes.
