Description Agostino Sarubbo gentoo-dev 2017-07-12 15:14:56 UTC
From ${URL} :

The get_build_id function in opncls.c in the Binary File Descriptor
(BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, allows attackers to cause a denial of service (heap-based buffer
over-read and application crash) via a crafted file in which a certain
size field is larger than a corresponding data field, as demonstrated
by mishandling within the objdump program.

@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.

Right now binutils-2.29 is not even keyworded yet. So this needs some time.
Comment 2 Andreas K. Hüttel gentoo-dev 2017-12-27 22:52:14 UTC
All affected versions are masked. No further cleanup (toolchain package). 

Nothing to do for toolchain here anymore. Please proceed.
