Description Tomas Hoger 2008-02-08 13:50:53 UTC

It was discovered that moin allowed overwrite of arbitrary file writable by user
running moin using crafted cookie with certain user IDs via directory traversal
flaw.

Fix in upstream HG:
http://hg.moinmo.in/moin/1.5/rev/e69a16b6e630

Sample exploit on milw0rm:
http://www.milw0rm.com/exploits/4957

Issue was reported for 1.5.x, but latest 1.6.1 in rawhide seems to be affected too.

Comment 2 Fedora Update System 2008-02-09 15:20:47 UTC

moin-1.5.8-3.fc7 has been submitted as an update for Fedora 7

Comment 3 Fedora Update System 2008-02-09 15:21:32 UTC

moin-1.5.8-3.fc8 has been submitted as an update for Fedora 8

Comment 4 Matthias Saou 2008-02-09 15:31:07 UTC

I've rebuilt patched packages for F-7, F-8, EL-4 and EL-5, and requested the
push to testing updates for the Fedora packages. I can't seem to find any
mention of 1.6.x being affected, nor can I see any fix having gone into the
upstream repository, and haven't yet looked at the code.
If there is more information as to 1.6.x's state, please let me know.

Comment 5 Tomas Hoger 2008-02-11 12:42:33 UTC

Matthias, I just look at the patch and it seems to apply to 1.6.x as well. 
Maybe there are other differences between 1.5.x and 1.6.x that make this patch
irrelevant for 1.6.x, but upstream will likely know better as they have not
applied it there (yet).  If 1.6.x is not affected, feel free to close-notabug
tracking bugs filed against devel.
