Description Mr. B 2009-08-18 19:40:14 UTC 
There exists a buffer overflow in the 2.5.8 (and below) prpl. 2.5.9 and 2.6.0

Reproducible: Always

Steps to Reproduce:
1. Send specially crafted SLP messages consecutively
2. Cause buffer overflow
3. Take control of system or cause crash




Pidgin should be bumped to 2.5.9 and 2.6.0.
Comment 1 Mr. B 2009-08-18 19:42:24 UTC 
Top line of the description was meant to say "2.5.9 and 2.6.0 are immune". Apologies.
Comment 2 7v5w7go9ub0o 2009-08-18 19:55:04 UTC 
I'm about to d/l 2.6.0; how's it working for you?

(given it's a zero-day, I'm always leery about "surprises" that might have gotten into the code :-) )

Very well, pity that MSN audio/video isn't working (though voice clips thereon are).
Just need to add:

farsight to USE

        farsight? (
                        media-plugins/gst-plugins-farsight
                        >=net-libs/farsight2-0.0.9 )

                $(use_enable farsight vv) \

...and of course: :P
#       strip-flags
#       replace-flags -O? -O2

er... I don't understand this ?



Otherwise, are voice and/or video working on other protocols?

TIA
