The libarchive team has investigated this report at:
libarchive/libarchive#2904
And we believe this should be rejected.

We agree with the reporter that under certain circumstances, a NULL pointer will be incremented by libarchive. This is technically Undefined Behavior according to the C standard, but it has no effect in this case, since under these conditions the incremented pointer is never dereferenced. We do plan to fix the code to avoid this UB, but do not feel it merits a CVE.

(This does not impact any Github product, so I choose "Composer" since I was forced to choose something.)

Hi,
GitHub can't make changes to this advisory because it's not in one of the GitHub Advisory Database's supported ecosystems, which means it is not issuing alerts.
