dotnet: .NET: Local file tampering via link following vulnerability

A flaw was found in .NET's System.Formats.Tar library. When extracting a specially crafted TAR archive containing symbolic links, the TarFile.ExtractToDirectory method may incorrectly follow those links and write files outside the intended extraction directory. An attacker could exploit this issu...

GHSA-WVRH-2F4M-924V ChatterBot: Symlink-Following Arbitrary Write via UbuntuCorpusTrainer

Summary ChatterBot's UbuntuCorpusTrainer.extract uses a predictable, home-rooted output directory /ubuntudata/ubuntudialogs with a check-then-create pattern if not os.path.exists: os.makedirs followed by tar.extractallpath=self.datapath. A local attacker who pre-plants a symlink at the predictabl...

GHSA-F9M7-VC86-P6JJ go.qbee.io/transport: Symlink-chain path traversal in tar extraction (one level outside destination)

Impact The go.qbee.io/transport library is affected by a symlink-chain path traversal vulnerability in its extractTar routine. The library's path validation is strictly lexical and fails to account for on-disk symlinks created earlier in the extraction process. Consequently, a crafted tar archive...
