Comment 1 Dhananjay Arunesh 2019-08-01 06:50:12 UTC

Created binutils tracking bugs for this issue:

Affects: fedora-all [bug 1735605]

Comment 2 Marco Benatto 2019-08-08 20:52:01 UTC

Statement:

This issue affects the binutils package version as shipped with Red Hat Enterprise Linux 7 and 8. The security impact was classified as 'Low' by the Red Hat Product Security Team.
Red Hat Enterprise Linux 5 and 6 are not affected as ld.gold is not shipped with any of these version.
This flaw also affects the binutils versions shipped with Red Hat Developer Toolset 7 and 8.

Comment 7 Marco Benatto 2019-08-09 14:32:23 UTC

There's an issue with ld.gold which allow an attacker to cause DoS. During the ELF file read the function File:: do_read() doesn't proper validate the start offset for reading, this leads to invalid memory access when executing memcpy() causing the program termination due to Segmentation Fault.
