GHSA-FXHP-MV3V-67QP `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,...

vim: command injection when decompressing .tgz archives

A flaw was found in Vim. When decompressing .tgz archives, the Vimuntar function builds shell commands using shellescape without the special flag. This allows a specially crafted archive filename to trigger Vim cmdline-special expansion and execute arbitrary commands in the context of the current...
