Descriptions
The OPENSSL_LH_flush() function, which empties a hash table, contains a bug that breaks reuse of the memory occuppied by the removed hash table entries. This function is used when decoding certificates or keys. If a long lived process periodically decodes certificates or keys its memory usage will expand without bounds and the process might be terminated by the operating system causing a denial of service. Also traversing the empty hash table entries will take increasingly more time. Typically such long lived processes might be TLS clients or TLS servers configured to accept client certificate authentication. The function was added in the OpenSSL 3.0 version thus older releases are not affected by the issue. Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2).
La función OPENSSL_LH_flush(), que vacía una tabla hash, contiene un error que rompe el reúso de la memoria ocupada por las entradas de la tabla hash eliminadas. Esta función es usado cuando son descodificados certificados o claves. Si un proceso de larga duración decodifica periódicamente certificados o claves, su uso de memoria será expandida sin límites y el proceso podría ser terminado por el sistema operativo causando una denegación de servicio. Además, recorrer las entradas vacías de la tabla hash llevará cada vez más tiempo. Normalmente, estos procesos de larga duración pueden ser clientes TLS o servidores TLS configurados para aceptar la autenticación de certificados de clientes. La función fue añadida en la versión 3.0 de OpenSSL, por lo que las versiones anteriores no están afectadas por el problema. Corregido en OpenSSL versión 3.0.3 (Afectado 3.0.0,3.0.1,3.0.2)
A memory leak flaw was found in OpenSSL, resulting in TLS servers and clients being halted by out-of-memory conditions, leading to a denial of service. An attacker needs to repeat actions continuously to trigger this vulnerability, resulting in a loss of application availability.
