CVE-2023-1108 : Security Advisory and Response

This CVE-2023-1108 involves an infinite loop vulnerability in the

sslconduit

component that occurs during a close operation. This flaw allows for a denial of service attack due to an unexpected handshake status update in

SslConduit

, leading to a situation where the loop never terminates.

Understanding CVE-2023-1108

This section delves into the details of CVE-2023-1108, highlighting its impact, technical description, affected systems, and mitigation strategies.

What is CVE-2023-1108?

The CVE-2023-1108 vulnerability stems from an infinite loop scenario within the

sslconduit

component during a close operation. This flaw enables attackers to initiate denial of service attacks by exploiting the unexpected handshake status update, resulting in a loop that never ends.

The Impact of CVE-2023-1108

The impact of CVE-2023-1108 is significant, as it allows threat actors to orchestrate denial of service attacks on vulnerable systems. By exploiting the flaw in

sslconduit

, attackers can manipulate handshake status updates to trigger an infinite loop, leading to service unavailability.
