Описание
Parsing arbitrary HTML can consume excessive CPU time, possibly leading to denial of service.
A flaw was found in golang.org/x/net/html. A remote attacker could provide specially crafted HTML, which, when parsed by the affected component, would consume excessive CPU resources. This could lead to a Denial of Service (DoS) condition, making the system unavailable to legitimate users.
Отчет
Red Hat rates this issue as Moderate with RH CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). A flaw was found in golang.org/x/net/html where parsing crafted HTML can consume excessive CPU time, leading to denial of service. Exploitation requires user interaction (a victim application parsing attacker-controlled HTML). Most Red Hat products that bundle golang.org/x/net do not use the html parser to process untrusted HTML in their supported execution paths.
Меры по смягчению последствий
Update affected Go applications to use golang.org/x/net version 0.55.0 or later. As a workaround, do not use golang.org/x/net/html to parse untrusted HTML content, or enforce timeouts on HTML parsing operations. Applications that do not parse arbitrary HTML are not affected.
