Re: A quartet of Linux local root vulns: DirtyAH6, PPPoEject, TUNderflow, and DiagSpill
An oss-security reply discusses packaging limits around four named Linux local root vulnerabilities.
Eli Schwartz posted a follow-up on an oss-security thread titled as four Linux local root flaws: DirtyAH6, PPPoEject, TUNderflow, and DiagSpill. The reply says the proposed idea needs package managers that generate dependency metadata at packaging time, support Provides, and handle an equals token in version fields. The excerpt includes no CVE identifiers, exploit details, or claims of in-the-wild use.
- Thread names DirtyAH6, PPPoEject, TUNderflow, and DiagSpill as Linux local roots.
- Reply concerns dynamic dependency metadata, Provides, and version-field tokens.
- Excerpt gives no CVE IDs, patches, or reports of exploitation.
From the original article
Posted by Eli Schwartz on Sep 21 Your idea requires three key Package Manager factors to work: - support for dynamically generated dependency metadata, computed during the packaging phase based on the results of compilation (will never be able to be statically parsed by tooling running against the collection of source recipes) - support for Provides functionality - handling of token = where occurs in the version…
