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-VMF3-W455-68VH node-tar applies PAX size override to intermediary GNU long-name/long-link headers, causing tar parser interpretation differential (file smuggling)

Summary tar node-tar applies a PAX extended header's size= record and other PAX overrides to the next header entry of any type, including intermediary metadata headers such as a GNU long-name L or long-link K entry. Per POSIX pax, a PAX extended header x describes the next file entry, not the...

node-tar: tar: node-tar: Arbitrary file overwrite and symlink poisoning via unsanitized linkpaths in archives

A flaw was found in the node-tar library. This vulnerability allows an attacker to craft malicious archives that, when extracted, can bypass intended security restrictions. This leads to arbitrary file overwrite and symlink poisoning, potentially allowing unauthorized modification of files on the...

USN-8138-1 rust-tar vulnerability

It was discovered that tar-rs incorrectly handled symlinks when unpacking a tar archive. If a user or automated system were tricked into processing a specially crafted tar archive, a remote attacker could use this issue to modify permissions of arbitrary directories outside the extraction root, a...

golang: archive/tar: Unbounded allocation when parsing GNU sparse map

A flaw was found in the archive/tar package in the Go standard library. tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A specially crafted tar archive with a pax header indicating a big number of sparse regions can cause a Go...
