Description Pedro Sampaio 2023-02-06 19:57:24 UTC

In Binutils, the field `file_table` of `struct module *module` is created without being initialized, and then its uninitialized field is used to assign `*file`, which is a pointer to a global variable `filename`. Later on when this variable is used, a segmentation fault occurs.

Comment 1 Nick Clifton 2023-02-07 12:35:02 UTC

Another vms-alpha specific fix.  Only affects binutils in RHEL 8/7/6.  See BZ 2167467 for more details on why bugs in the vms-alpha alpha support is restricted to these releases.

Comment 6 Siddhesh Poyarekar 2023-03-01 17:35:15 UTC

This does not affect gdb in RHEL or Fedora; gdb does not have or build the affected code.

Comment 7 Keith Seitz 2023-03-01 17:58:42 UTC

While bfd/vms-alpha.c is included in the gdb srpm, gdb.spec only enables
targets that are supported by RHEL (ppc64/ppc64le, aarch64, s390x, x86_64).
This file is therefore never built in gdb.
