Description Agostino Sarubbo gentoo-dev 2017-05-04 15:37:58 UTC
From ${URL} :

Rpcbind does not consider the maximum RPC data size during memory allocation for XDR strings, which allows remote attackers to cause a denial of service (memory consumption with no 
subsequent free) via a crafted UDP packet to port 111, aka rpcbomb.


@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
Comment 1 Patrick McLean gentoo-dev 2017-05-08 18:42:12 UTC
Bump done, will need to be re-stabilized. Should be fine to stabilize, those patches look safe.

Remaining arches are not part of security supported architectures, proceeding with security. Arches please stabilize as soon as possible to secure package.

Comment 13 Valeriy Malov 2017-06-06 11:34:03 UTC
There's a typo in glsa-201706-07.xml / on glsa page, rpcbind affected/unaffected version is set to "0.2.4-r", which breaks glsa-check -t all
