#246: cabal-install's tar unpacking does not cope well with links ---------------------------------+------------------------------------------ Reporter: duncan | Owner: Type: defect | Status: closed Priority: normal | Milestone: Component: cabal-install tool | Version: 1.2.3.0 Severity: normal | Resolution: fixed Keywords: | Difficulty: very easy (<1 hour) Ghcversion: 6.8.2 | Platform: ---------------------------------+------------------------------------------ Changes (by kolmodin): * status: new => closed * resolution: => fixed Comment: {{{ Tue Mar 4 20:42:55 CET 2008 Lennart Kolmodin * Fix defect when unpacking tar files containing links There were two issues; * Unpacking links that point to files not yet unpacked * Used the link target as absolute path, but it's relative This patch addresses both issues, which is ticket #246. There may still be errors if a link refer to another link which has not been unpacked yet. }}} We should think of sanity (and security) too, what if a link points outside the working directory? -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/246#comment:1 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
