Descriptions

Incorrect conversion of certain invalid paths to valid, absolute paths in Clean in path/filepath before Go 1.17.11 and Go 1.18.3 on Windows allows potential directory traversal attack.

En filepath.Clean en path/filepath en Go versiones anteriores a 1.17.11 y en 1.18.x antes de 1.18.3 en Windows, las rutas inválidas como .\c: podían convertirse en rutas válidas (como c: en este ejemplo).

An update that solves four vulnerabilities and has one errata is now available. This update for go1.17 fixes the following issues. Fixed crypto/rand rand.Read hangs with extremely large buffers. Fixed crypto/tls session tickets lack random ticket_age_add. Fixed path/filepath Clean returns 'c:' on Windows. Fixed os/exec empty Cmd.Path can result in running unintended binary on Windows.
