UBUNTU-CVE-2026-116133 (CVE-2026-116133)

Vulnerability from osv_ubuntu – Published: 2026-10-28 18:17 – Updated: 2026-11-06 23:21 – Source website

Details

HTTP::Body versions before 1.23_01 for Perl allow CPU exhaustion via quadratic rescanning of a multipart body with a missing or malformed boundary. Before the first part, and between parts, the multipart parser searches the whole buffered body for the next boundary. On a miss it keeps everything and searches again from the start when the next chunk arrives. A body with no boundary, or with a delimiter followed by neither CRLF nor "--", is therefore rescanned on every chunk, taking time quadratic in its size. A remote attacker can exhaust worker CPU with a few such requests.

Severity
