Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Coder (github.com/coder/coder/v2) versions 2.24.0 up to 2.29.17, 2.30.0 up to 2.32.7, 2.33.0 up to 2.33.8, and 2.34.0 up to 2.34.2 are affected. An authenticated user who can reach the provisioner daemon serve endpoint can send a small message declaring a very large file size, causing an out-of-memory crash that takes down the coderd process for the whole deployment. Upgrade to 2.29.17, 2.32.7, 2.33.8, or 2.34.2, matching your release line. Restricting access to the provisioner daemon serve endpoint to trusted service accounts is a workaround.
