Short explanation
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 [S0]. A remote attacker can exhaust worker CPU with a few such requests [S0].
This vulnerability allows remote attackers to exhaust server worker CPU resources and cause service disruption using only a few crafted requests [S0].
What should be done?
- Follow the vendor advisory to apply necessary updates.
- Review the provided patch references [S0].
Chain of evidence and sources
HTTP::Body 1.23_01 öncesi sürümler, eksik veya hatalı sınır etiketine sahip gövdelerde CPU tükenmesine neden olur [S0].
Uzaktaki bir saldırgan bu durumu kullanarak işçi CPU kaynaklarını tüketebilir [S0].
Show the technical text from the sources
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.
