Description Alexander Bergmann 2017-06-19 09:05:58 UTC

The _bfd_vms_slurp_etir function in bfd/vms-alpha.c in the Binary File
Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28,
allows remote attackers to cause a denial of service (buffer overflow and
application crash) or possibly have unspecified other impact via a crafted
binary file, as demonstrated by mishandling of this file during "objdump -D"

Comment 1 Alexander Bergmann 2017-06-19 09:09:34 UTC
Reproducer from https://sourceware.org/bugzilla/show_bug.cgi?id=21579 didn't work on SLE or openSUSE.

#> objdump -D testcase.cve-2017-9745 
objdump: testcase.cve-2017-9745: File format not recognized

However the affected/fixed code is present.
Comment 2 Michael Matz 2017-06-20 13:43:34 UTC
We don't enable the VMS-alpha subtarget in our binutils, the code isn't
compiled, we aren't affected.
