p2p use flag is disabled by default in Gentoo, this will probably protect most users.
There's a patch:
Not sure if they'll produce a new release soon.
*** Bug 547490 has been marked as a duplicate of this bug. ***
it's a race, I've commited 2.4-r1 to fix this bug, but bug #524928 is also being fixed and stabilized. Which bug will we stabilize for first?
2.4-r1 is already stable. Going to cleanup and vote.

This vulnerability on its own does not merit a GLSA, however adding this together with the GLSA for bug 524928
Heap-based buffer overflow in wpa_supplicant 1.0 through 2.4 allows remote
attackers to cause a denial of service (crash), read memory, or possibly
execute arbitrary code via crafted SSID information in a management frame
when creating or updating P2P entries.
Arches and Maintainer(s), Thank you for your work.
