Описание
libcurl might in some circumstances reuse the wrong connection when asked to
do Negotiate-authenticated ones, even when they are set to use different
'services'.
libcurl features a pool of recent connections so that subsequent requests can
reuse an existing connection to avoid overhead.
When reusing a connection a range of criteria must be met. Due to a logical
error in the code, a request that was issued by an application could
wrongfully reuse an existing connection to the same server that was
authenticated using different services.
A flaw was found in libcurl. A logical error in the connection pooling mechanism may cause libcurl to reuse an authenticated connection for an unintended service. This could allow an application to wrongfully reuse an existing connection to the same server that was authenticated for a different service, potentially leading to unauthorized access or information disclosure.
Отчет
This is an Important flaw in libcurl where a logical error in connection pooling can lead to unauthorized connection reuse. When an application uses Negotiate authentication with different service names on the same hostname and port, libcurl might incorrectly reuse an existing authenticated connection for an unintended service. This could result in information disclosure or unauthorized access to resources, bypassing intended service isolation.
