Description David Walser 2018-02-10 21:21:56 CET
Ubuntu has issued an advisory on February 7:

Despite the description saying only < 2.0 is affected, our 2.0 snapshot from last year was too old to include the fix (which was committed in December):

Note that the page above also references two other non-CVE security fixes in addition to the CVE fix.

Mageia 6 is also affected.
Comment 1 David Walser 2018-02-10 21:23:32 CET
Mageia 5 is also affected (but we don't need to push a fix there).

Whiteboard: (none) => MGA6TOO

Comment 2 Mike Rambo 2018-05-11 21:57:08 CEST
Cauldron has been recently updated to a version which is not vulnerable. Two of the patches are already applied and 9fcc0a72f09e6e1aa46ddcc997d3dcae87d4b416 does not apply. That patch also did not apply to mga6. I did not do anything with mga#22455 as I do not know if the suggested changes are valid. Leaving that for the maintainer. This update fixes the security issue.

Updated package uploaded for Mageia 6.


Updated miniupnpc package fixes security vulnerability:

It was discovered that miniupnpc contained a heap buffer overflow in
parseelt (minixml.c - no CVE assigned).

It was discovered that miniupnpc also contained a memory corruption
(invalid read, SIGSEGV) in NameValueParserEndElt (upnpreplyparse.c)
while handling two consecutive malformed SOAP requests (CVE-2017-1000494).


Updated packages in core/updates_testing:

from miniupnpc-2.0.20170509-1.1.mga6.src.rpm

Comment 3 Len Lawrence 2018-05-12 21:44:03 CEST
Mageia 6, x86_64
Had a look at this, encouraged by the report from PC LX of previous testing.
Searched for PoCs and found tests athttps://github.com/miniupnp/miniupnp/issues/268 which involved a daemon by the looks of it, called miniupnpd.  The tests included a couple of message blocks to be sent via a specified port to another IP address, piping through xxd and netcat.  I could not find xxd or miniupnpd so gave up on that.

for more information.
No IGD UPnP Device found on the network !

That looks like a full stop to me so I shall have to hand this over to PC LX.

MGA6-32 on IBM Thinkpad R50e MATE
No installation issues
Got no further than Len. I guessed that the IP address in the testcase of bug 20851 would be the address of the router ??? But of course port 2555 or 2222 is blocked and I'm not very eager to open up ports for testing.

Quick preparatory word.
