CVE-2020-29529 – go-slug: partial protection against zip slip attacks

https://notcve.org/view.php?id=CVE-2020-29529

HashiCorp go-slug up to 0.4.3 did not fully protect against directory traversal while unpacking tar archives, and protections could be bypassed with specific constructions of multiple symlinks. Fixed in 0.5.0. HashiCorp go-slug hasta la versión 0.4.3 no protegía completamente contra el cruce de directorios al desempaquetar archivos tar, y las protecciones podían ser eludidas con construcciones específicas de múltiples enlaces simbólicos. Corregido en 0.5.0. • https://github.com/hashicorp/go-slug/compare/v0.4.3...v0.5.0 https://github.com/hashicorp/go-slug/pull/12 https://github.com/hashicorp/go-slug/releases/tag/v0.5.0 https://securitylab.github.com/advisories/GHSL-2020-262-zipslip-go-slug https://access.redhat.com/security/cve/CVE-2020-29529 https://bugzilla.redhat.com/show_bug.cgi?id=1914238 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •
