ubuntu

October 11, 2012

Several security issues were fixed in MoinMoin.

Summary

Several security issues were fixed in MoinMoin.

Software Description:

- 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)
