Описание
c-ares is an asynchronous resolver library. Versions 1.32.3 through 1.34.5 terminate a query after maximum attempts when using read_answer() and process_answer(), which can cause a Denial of Service. This issue is fixed in version 1.34.6.
A flaw was found in c-ares. This vulnerability allows a Denial of Service (DoS) via terminating a query after maximum attempts when using read_answer() and process_answer() functions.
Отчет
This vulnerability is rated Moderate for Red Hat products. The flaw in c-ares can lead to a Denial of Service when the library is used to resolve queries, specifically when read_answer() and process_answer() functions are called and a query terminates after maximum attempts. This could impact applications that rely on c-ares for asynchronous DNS resolution.
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.
