Comment 1 Ben Beasley 2025-07-19 12:30:24 UTC

According to https://www.cve.org/CVERecord?id=CVE-2025-53817, the CVE arises from a defect in NArchive::NCom::CHandler::GetStream; https://securitylab.github.com/advisories/GHSL-2025-059_7-Zip/ provides further details.

The 7-Zip code bundled and forked in advancecomp does not contain an NCom handler, and no code resembling the context around the bug in the GitHub advisory could be found. It is therefore reasonable to presume that advancecomp is not affected by this particular CVE.
