Description Aleksandr Wagner (Kivak) 2017-09-27 11:29:40 UTC 
CVE-2017-14729 (https://nvd.nist.gov/vuln/detail/CVE-2017-14729):

The *_get_synthetic_symtab functions in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, do not ensure a unique PLT entry for a symbol, which allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted ELF file, related to elf32-i386.c and elf64-x86-64.c.

Patch added to gentoo/binutils-2.29.1 branch
Comment 2 Andreas K. Hüttel archtester gentoo-dev 2017-12-27 22:53:19 UTC 
All affected versions are masked. No further cleanup (toolchain package). 

Nothing to do for toolchain here anymore. Please proceed.
