Description Hanno Böck gentoo-dev 2015-04-23 14:57:51 UTC
This sounds serious:

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.

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?
Comment 3 Yury German Gentoo Infrastructure gentoo-dev 2015-04-27 21:17:54 UTC
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

CVE-2015-1863 (
  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.
