Descriptions

Buffer overflow in the SnifferDecompress function in wiretap/ngsniffer.c in the DOS Sniffer file parser in Wireshark 1.10.x before 1.10.10 and 1.12.x before 1.12.1 allows remote attackers to cause a denial of service (application crash) via a crafted file that triggers writes of uncompressed bytes beyond the end of the output buffer.

Desbordamiento de buffer en la función SnifferDecompress en wiretap/ngsniffer.c en el analizador de ficheros DOS Sniffer en Wireshark 1.10.x anterior a 1.10.10 y 1.12.x anterior a 1.12.1 no previene la sobreescritura de datos durante operaciones de copia, lo que permite a atacantes remotos causar una denegación de servicio (caída de la aplicación) a través de un fichero manipulado que provoca escrituras de bytes descomprimidos más allá del final del buffer de salida.

Wireshark is a network protocol analyzer. It is used to capture and browse the traffic running on a computer network. Multiple flaws were found in Wireshark. If Wireshark read a malformed packet off a network or opened a malicious dump file, it could crash or, possibly, execute arbitrary code as the user running Wireshark. Several denial of service flaws were found in Wireshark. Wireshark could crash or stop responding if it read a malformed packet off a network, or opened a malicious dump file.
