Описание

Socket.IO is an open source, real-time, bidirectional, event-based, communication framework. Prior to versions 3.3.5, 3.4.4, and 4.2.6, a specially crafted Socket.IO packet can make the server wait for a large number of binary attachments and buffer them, which can be exploited to make the server run out of memory. This issue has been patched in versions 3.3.5, 3.4.4, and 4.2.6.

A flaw was found in Socket.IO, an open-source, real-time communication framework. A remote attacker could exploit this vulnerability by sending specially crafted Socket.IO packets that cause the server to buffer a large number of binary attachments. This excessive buffering can lead to the server running out of memory, resulting in a Denial of Service (DoS) for legitimate users.

Меры по смягчению последствий

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
