Description Tim Sammut (RETIRED) gentoo-dev 2010-10-22 07:17:11 UTC
From $url:

Mono ASP.NET implementation is vulnerable to the padding oracle attack, i.e. it leaks some details when invalid padding is being decrypted. However it is not possible to download the web.config  file from the web server (and retrieve the keys or other data from it). The actual severity of attack depends on the web application.

Version affected:

    * Mono 1.x and 2.x 

Version fixed:

    * GIT (under testing)
Comment 1 Tim Sammut (RETIRED) gentoo-dev 2010-11-22 04:26:16 UTC
Mono 2.8.1 contains this fix and has been released upstream.
Comment 2 Stefan Behte (RETIRED) gentoo-dev Security 2010-11-29 22:22:25 UTC
Is it ok to go stable?
Comment 3 Pacho Ramos gentoo-dev 2010-11-29 22:34:03 UTC
I don't think mono 2.8 is ready to go stable yet :-/
Comment 4 Tim Sammut (RETIRED) gentoo-dev 2011-03-22 22:01:37 UTC
Fixed packages have been stabilized via 352808 and, for ppc only, 359651.
