RHBA-2013:0498 - Bug Fix Advisory

Topic

Updated binutils packages that fix two bugs are now available for Red Hat
Enterprise Linux 6.

Description

The binutils packages provide a set 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).

This update fixes the following bugs:

• In order to display a non-printing character, the readelf utility adds the

"0x40" string to the character. However, readelf previously did not add that
string when processing multibyte characters, so that multibyte characters in the
ELF headers were displayed incorrectly. With this update, the underlying code
has been corrected and readelf now displays multibyte and non-ASCII characters
correctly. (BZ#773526)

• Under certain circumstances, the linker could fail to produce the GNU_RELRO

segment when building an executable requiring GNU_RELRO. As a consequence, such
an executable failed upon start-up. This problem affected also the libudev
library so that the udev utility did not work. With this update, the linker has
been modified so that the GNU_RELRO segment is now correctly created when it is
needed, and utilities such as udev now work correctly. (BZ#825736)

All users of binutils are advised to upgrade to these updated packages, which
fix these bugs.
