HTTP::Body versions before 1.24_01 for Perl allow memory exhaustion via unbounded buffering of chunked request bodies

Impact

HTTP::Body versions before 1.24_01 for Perl are vulnerable to memory exhaustion via unbounded buffering of chunked request bodies, allowing a remote attacker to exhaust memory. The weakness occurs in chunked mode when no content length is given. This can cause the parser to wait forever and grow the buffer with each added chunk.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

What to do

Upgrade to HTTP-Body 1.24_01 or later.

Original source description

HTTP::Body versions before 1.24_01 for Perl allow memory exhaustion via unbounded buffering of chunked request bodies.

In chunked mode, used when no content length is given, add() holds each chunk in memory until all of it has arrived. A line that is not a chunk-size line, a size line without CRLF, or a size too large to fit an integer leaves the parser waiting forever, and every later add() grows the buffer.

A remote attacker can exhaust memory in applications that pass chunked request bodies to HTTP::Body.
