- ------------------------------------------------------------------------- Debian LTS Advisory DLA-3947-1 [email protected] https://www.debian.org/lts/security/ Abhijith PA November 06, 2024 https://wiki.debian.org/LTS

Package : puma Version : 4.3.8-1+deb11u3 CVE ID : CVE-2024-21647 CVE-2024-45614

Two vulnerabilities have been fixed in puma, a threaded HTTP server for Ruby/Rack applications.

CVE-2024-21647

Incorrect behavior when parsing chunked transfer encoding bodies in a way that allowed HTTP request smuggling. Fixed versions limits the size of chunk extensions. Without this limit, an attacker could cause unbounded resource (CPU, network bandwidth) consumption.

CVE-2024-45614

Clients could clobber values set by intermediate proxies (such as X-Forwarded-For) by providing a underscore version of the same header (X-Forwarded_For). Any users relying on proxy set variables is affected.

For Debian 11 bullseye, these problems have been fixed in version 4.3.8-1+deb11u3.

We recommend that you upgrade your puma packages.
