Description Adam Mariš 2017-08-21 12:44:15 UTC

The bfd_mach_o_read_symtab_strtab function in bfd/mach-o.c in the
Binary File Descriptor (BFD) library (aka libbfd), as distributed in
GNU Binutils 2.29 and earlier, allows remote attackers to cause an out
of bounds heap write and possibly achieve code execution via a crafted
mach-o file.

Comment 2 Pedro Yóssis Silva Barbosa 2017-09-22 12:53:42 UTC

The issues did not affect Red Hat Enterprise Linux 5, 6, 7 and devtools 4, 6 and 7.
Red Hat does not ship binutils compiled with the --enable-targets=all configuration. Therefore, Product Security Team was not able to reproduce the issues.
