Comment 2 Mark Wielaard 2025-02-18 10:21:57 UTC

Note that this CVE was filed without following the upstream SECURITY policy:
https://sourceware.org/cgit/elfutils/tree/SECURITY
This is NOT a security issue according to upstream policy.
It was filed against GNU as vendor but elfutils is not a GNU package.

Upstream request that people who report suspected security vulnerabilities
report them through the contacts in the SECURITY policy and not through non-affiliated CNAs.
