Ubuntu Security Notice USN-6597-1
January 25, 2024

puma vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 23.10
- Ubuntu 23.04


Puma could be made to consume resources if it received specially crafted
network traffic.

Software Description:
- puma: threaded HTTP 1.1 server for Ruby/Rack applications


It was discovered that Puma incorrectly handled parsing chunked transfer
encoding bodies. A remote attacker could possibly use this issue to cause
Puma to consume resources, leading to a denial of service.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 23.10:
   puma                            5.6.5-4ubuntu2.1

Ubuntu 23.04:
   puma                            5.6.5-3ubuntu1.2

In general, a standard system update will make all the necessary changes.
