Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2021-07-20 22:52:14 UTC
CVE-2021-32773:

Racket is a general-purpose programming language and an ecosystem for language-oriented programming. In versions prior to 8.2, code evaluated using the Racket sandbox could cause system modules to incorrectly use attacker-created modules instead of their intended dependencies. This could allow system functions to be controlled by the attacker, giving access to facilities intended to be restricted. This problem is fixed in Racket version 8.2. A workaround is available, depending on system settings. For systems that provide arbitrary Racket evaluation, external sandboxing such as containers limit the impact of the problem. For multi-user evaluation systems, such as the `handin-server` system, it is not possible to work around this problem and upgrading is required.

Patch: https://github.com/racket/racket/commit/6ca4ffeca1e5877d44f835760ad89f18488d97e1

Please bump.
