HTTP::Body versions before 1.23_01 for Perl allow memory exhaustion via an unbounded multipart part header block

Impact

HTTP::Body versions before 1.23_01 for Perl are vulnerable to memory exhaustion via an unbounded multipart part header block, allowing a remote attacker to exhaust worker memory with a single request. The multipart parser has no limit on the size or number of lines of the part's header block. This can lead to memory exhaustion.

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

What to do

Upgrade to HTTP-Body 1.23_01 or later.

Original source description

HTTP::Body versions before 1.23_01 for Perl allow memory exhaustion via an unbounded multipart part header block.

The multipart parser takes everything up to the first blank line after a boundary as the part's header block, with no limit on its size or number of lines. Every line is stored in the part's header hash, so a block of short lines costs about 60 bytes of memory per input byte.

A remote attacker can exhaust worker memory with a single request.
