Description Adam Mariš 2017-08-21 12:43:58 UTC

The alpha_vms_object_p function in bfd/vms-alpha.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 vms alpha
file.

Comment 2 Pedro Yóssis Silva Barbosa 2017-09-22 12:28:29 UTC

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