CVE-2026-50163 oras-go: Hardlink entry with relative Linkname escapes extract dir via process CWD resolution in `oras-go` tar extraction

oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2, ensureLinkPath in content/file/utils.go:262-275 validates a hardlink target relative to the extract base but returns the unresolved target, causing os.Link"victim.secret", "/payload.tar.gz/evilcwdlink" to resolve header.Linkname...

`oras-go` tar extraction: Hardlink entry with relative Linkname escapes extract dir via process CWD resolution

Root cause The tar-extraction helper ensureLinkPath at content/file/utils.go:262-275 validates that a hardlink's target resolves inside the extract base, but then returns the original unresolved target string back to the caller: go func ensureLinkPathbaseAbs, baseRel, link, target string string,...

EUVD-2026-37712

A stack-based buffer overflow exists in the rawtoheader function in src/microtar.c in rxi microtar 0.1.0. The function copies the 100-byte name and linkname fields of a TAR header with strcpy without guaranteeing null termination of the source. The POSIX ustar format permits these fixed-width...

OESA-2026-2678 perl-Archive-Tar security update

archive::Tar provides an object oriented mechanism for handling tar files. It provides class methods for quick and easy files handling while also allowing for the creation of tar file objects for custom manipulation. If you have the IO::Zlib module installed, Archive::Tar will also support...

CVE-2026-44340

PraisonAI is a multi-agent teams system. Prior to version 4.6.37, the safeextractall helper that all recipe pull, recipe publish, and recipe unpack flows route through validates each archive member's name for absolute paths, .. segments, and resolved-path escape — but does not validate...

CVE-2026-43623

A flaw was found in microtar. A remote attacker could exploit a stack-based buffer overflow vulnerability in the rawtoheader function by supplying a crafted TAR archive with non-null-terminated name or linkname fields. This flaw allows the attacker to corrupt adjacent stack memory, which may lead...
