Description Kristian Fiskerstrand (RETIRED) gentoo-dev 2015-02-04 14:49:02 UTC
From $URL:
is almost 1 year old, and still not fixed in glibc trunk.

I have verified that the test case from it fails with libc6
2.19-0ubuntu6.5 and current trunk glibc.

Don't know if it's exploitable, but it seems like it could easily be.

(I'll see if I can fix it in the mean time.)

From upstream bug: Fixed in 2.21.
Comment 2 Yury German Gentoo Infrastructure gentoo-dev 2015-02-15 23:55:55 UTC
2.21 is not available for stabilization yet as far as I see. Setting it back to ebuild until it is ready.

fix is also in glibc-2.20-r2 now
