Описание
When curl retrieves an HTTP response, it stores the incoming headers so that
they can be accessed later via the libcurl headers API.
However, curl did not have a limit in how many or how large headers it would
accept in a response, allowing a malicious server to stream an endless series
of headers and eventually cause curl to run out of heap memory.
A flaw was found in the Curl package. Curl allows a malicious server to stream an endless series of headers to a client due to missing limit on header quantity, eventually causing curl to run out of heap memory, which may lead to a crash.
Отчет
This issue does not affect the Curl package as shipped in Red Hat Enterprise Linux 6, 7, 8, and 9.
