[Bug 312536] Re: Stop honoring digital signatures based on MD5 hashes

2009-01-21 Thread Miron Cuperman
A successful attack would mean that the attackers would have a rogue CA.
They would then be able to generate a bogus certificate for any site
without any additional resources.  This issue should therefore be
considered critical in my opinion.  The benefit to an attacker would
justify using considerable resources in generating the rogue CA cert.

I do think that the end-user should be able to override the security
weakness warning.

As long as the end-user can override the warning, they are still able to
continue with existing workflows based on their judgment.

Also, the warning would encourage CA's and web sites to move to SHA more
quickly.

[Bug 103747] metacity (ubuntu) + xcompmgr : issue with XShapeCombineRectangles

2007-04-06 Thread Cristian Miron
Public bug reported:

Binary package hint: metacity

I'm using Ubuntu 6.10, metacity version 2.16.3-0ubuntu2 , and xcompmgr. In my 
application, when I'm using  XShapeCombineRectangles to cut rectangles from its 
windows, the window doesn't have a hole in it. Once I close xcompmgr, the hole 
appears ok. I'll attach soon a small application to demonstrate this. 
Any ideas?

They would then be able to generate a bogus certificate for any site

[Bug 251304] Re: Pidgin XMPP TLS/SSL Man in the Middle attack

2008-08-05 Thread Miron Cuperman
I don't think so.  I would have done it, but not certain of the
procedure.

[Bug 312536] [NEW] Stop honoring digital signatures based on MD5 hashes

2008-12-30 Thread Miron Cuperman
*** This bug is a security vulnerability ***

Public security bug reported:

In http://www.win.tue.nl/hashclash/rogue-ca/ , a CA cert was created
that is accepted by Firefox.  This allows any web site to be
impersonated.

See upstream https://bugzilla.mozilla.org/show_bug.cgi?id=471539 .

This may also apply to other PKI enabled packages in Ubuntu that accept
MD5, including Thunderbird, Evolution, and anything that depends on
openssl.

[Bug 103747] metacity (ubuntu) + xcompmgr : issue with XShapeCombineRectangles

2007-04-06 Thread Cristian Miron
Public bug reported:

Binary package hint: metacity

I'm using Ubuntu 6.10, metacity version 2.16.3-0ubuntu2 , and xcompmgr. In my 
application, when I'm using  XShapeCombineRectangles to cut rectangles from its 
windows, the window doesn't have a hole in it. Once I close xcompmgr, the hole 
appears ok. I'll attach soon a small application to demonstrate this. 
Any ideas?

Thanks,
Cristian Miron

[Bug 312536] Re: Stop honoring digital signatures based on MD5 hashes

2009-01-21 Thread Miron Cuperman
A successful attack would mean that the attackers would have a rogue CA.
They would then be able to generate a bogus certificate for any site
without any additional resources.  This issue should therefore be
considered critical in my opinion.  The benefit to an attacker would
justify using considerable resources in generating the rogue CA cert.

I do think that the end-user should be able to override the security
weakness warning.

As long as the end-user can override the warning, they are still able to
continue with existing workflows based on their judgment.

Also, the warning would encourage CA's and web sites to move to SHA more
quickly.
