Descriptions

The read_binary function in buffer.c in pgpdump before 0.30 allows context-dependent attackers to cause a denial of service (infinite loop and CPU consumption) via crafted input, as demonstrated by the \xa3\x03 string.

La función read_binary en buffer.c en pgpdump en versiones anteriores a 0.30 permite a atacantes dependientes del contexto provocar una denegación de servicio (bucle infinito y consumo de CPU) a través de una entrada manipulada, según lo demostrado por la cadena \xa3\x03.

pgpdump version 0.29 suffers from an endless loop parsing issue that can lead to a denial of service.
