Descriptions

A buffer over-read was discovered in libntlmauth in Squid 2.5 through 5.6. Due to incorrect integer-overflow protection, the SSPI and SMB authentication helpers are vulnerable to reading unintended memory locations. In some configurations, cleartext credentials from these locations are sent to a client. This is fixed in 5.7.

Se descubrió una lectura excesiva del búfer en libntlmauth en Squid 2.5 a 5.6. Debido a una protección incorrecta contra el desbordamiento de enteros, los asistentes de autenticación SSPI y SMB son vulnerables a la lectura de ubicaciones de memoria no deseadas. En algunas configuraciones, las credenciales en texto sin cifrar de estas ubicaciones se envían a un cliente. Esto se solucionó en 5.7.
