RHBA-2017:1420 - Bug Fix Advisory

Topic

Updated devtoolset-6-binutils packages that fix one bug are now available for Red Hat Developer Toolset 6.

Description

Binutils is a collection of binary utilities, including ar (for creating, modifying, and extracting from archives), as (a family of GNU assemblers), gprof (for displaying call graph profile data), ld (the GNU linker), nm (for listing symbols from object files), objcopy (for copying and translating object files), objdump (for displaying information from object files), ranlib (for generating an index for the contents of an archive), readelf (for displaying detailed information about binary files), size (for listing the section sizes of an object or archive file), strings (for listing printable strings from files), strip (for discarding symbols), and addr2line (for converting addresses to file and line). The devtoolset-6-binutils packages provide the Red Hat Developer Toolset version of binutils.

This update fixes the following bug:

• As an optimization, binutils previously ceased to generate Procedure Linkage Table (PLT) entries for executables for the 32-bit and 64-bit Intel architectures when a GOT entry was sufficient. As a consequence, tools using the PLT entries failed to work with the produced executables. In addition, the LD_AUDIT system feature for modifying the system's behavior when loading binaries also failed to work. With this update, the optimization has been reverted, and the described problems no longer occur. (BZ#1454326, BZ#1454328)

Users of devtoolset-6-binutils are advised to upgrade to these updated packages, which fix this bug.
