Descriptions

Heap-based buffer overflow in Actian Pervasive PSQL v12.10 and Zen v13 allows remote attackers to execute arbitrary code via crafted traffic to TCP port 1583. The overflow occurs after Server-Client encryption-key exchange. The issue results from an integer underflow that leads to a zero-byte allocation. The _srvLnaConnectMP1 function is affected.

El desbordamiento de búfer en la región heap de la memoria en Actian Pervasive PSQL versión 12.10 y Zen versión 13 permite a los atacantes remotos ejecutar código arbitrario por medio de un tráfico creado hacia el puerto TCP 1583. El desbordamiento ocurre después del intercambio de claves de cifrado de Cliente-Servidor. El problema resulta en un subdesbordamiento de enteros que conlleva a una asignación de cero bytes. La función _srvLnaConnectMP1 se ve afectada
