Description Aleksandr Wagner (Kivak) 2017-09-26 20:10:18 UTC

CVE-2017-14745 (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-14745):

The *_get_synthetic_symtab functions in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, interpret a -1 value as a sorting count instead of an error flag, which allows remote attackers to cause a denial of service (integer 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.

All affected versions are masked. No further cleanup (toolchain package). 

Nothing to do for toolchain here anymore. Please proceed.
