Описание
During the TLS 1.3 handshake if multiple messages are sent in records that span encryption level boundaries (for instance the Client Hello and Encrypted Extensions messages), the subsequent messages may be processed before the encryption level changes. This can cause some minor information disclosure if a network-local attacker can inject messages during the handshake.
A TLS connection handling flaw has been discovered in the golang crypto/tls library. During the TLS 1.3 handshake if multiple messages are sent in records that span encryption level boundaries (for instance the Client Hello and Encrypted Extensions messages), the subsequent messages may be processed before the encryption level changes. This can cause some minor information disclosure if a network-local attacker can inject messages during the handshake.
Отчет
The data leak after exploitation of this vulnerability is minor, data such as Handshake message contents that should have been processed only after switching to a stronger TLS 1.3 encryption level, Protocol state details such as which handshake message was processed when, Timing and ordering information about the TLS 1.3 state.
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.
