Description Agostino Sarubbo gentoo-dev 2014-09-16 09:07:32 UTC
From ${URL} :

libceph: do not hard code max auth ticket len

We hard code cephx auth ticket buffer size to 256 bytes. This isn't enough for
any moderate setups and, in case tickets themselves are not encrypted, leads to
buffer overflows (ceph_x_decrypt() errors out, but ceph_decode_copy() doesn't -
it's just a memcpy() wrapper). Since the buffer is allocated dynamically
anyway, allocated it a bit later, at the point where we know how much is going
to be needed.


@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 Yixun Lan gentoo-dev 2014-09-18 14:50:12 UTC
I'm CCing kernel team, since it's a kernel patch...

also notice it has already been CCed to stable-kernel mailing list,so guess it will eventually goes to sys-kernel/gentoo-sources-3.14.x? thanks
Comment 2 Thomas Deutschmann gentoo-dev Security 2016-11-21 15:01:21 UTC
The kernel patch landed in linux-3.17-rc5.

It was backported to


sys-kernel/gentoo-sources-3.2.x are not available.

sys-kernel/gentoo-sources-3.4.x has no stable ebuild containing the fix, =sys-kernel/gentoo-sources-3.4.113 will be stabilized in bug 599526 at the moment.

sys-kernel/gentoo-sources-3.10.x has a stable ebuild since >=sys-kernel/gentoo-sources-3.10.61.

sys-kernel/gentoo-sources-3.12.x has a stable ebuild since >=sys-kernel/gentoo-sources-3.12.30.

sys-kernel/gentoo-sources-3.16.x are not available.

Nothing to do here. Stable users of the 3.4 branch are already in trouble/on their own, and belatedly stabilising isn't going to help them.

What is the status of this finally? :/ Looks that the stabilization was interrupted
Comment 9 Yury German Gentoo Infrastructure gentoo-dev 2017-04-30 19:25:20 UTC
Can we get a status on this?
Comment 10 Pacho Ramos gentoo-dev 2017-12-04 13:06:37 UTC
this is probably obsolete as the only affected version in the tree could be 3.10.x and now we have a new enough version in the tree to fix it

Unable to check for sanity:

> no match for package: =sys-kernel/gentoo-sources-3.4.113
Comment 12 Yury German Gentoo Infrastructure gentoo-dev 2020-04-10 21:22:45 UTC
3.X is not in tree.
