CVE-2015-2155

La impresora de fuerza en tcpdump en versiones anteriores a 4.7.2 permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de vectores no especificados.

The Tcpdump program could crash when processing a malformed OLSR payload when the verbose output flag was set. The application decoder for the Ad hoc On-Demand Distance Vector protocol in Tcpdump fails to perform input validation and performs unsafe out-of-bound accesses. The application will usually not crash, but perform out-of-bounds accesses and output/leak larger amounts of invalid data, which might lead to dropped packets. It is unknown if a payload exists that might trigger segfaults. It was discovered that tcpdump incorrectly handled printing PPP packets. A remote attacker could use this issue to cause tcpdump to crash, resulting in a denial of service, or possibly execute arbitrary code. Several vulnerabilities have been discovered in tcpdump. These vulnerabilities might result in denial of service (application crash) or, potentially, execution of arbitrary code. .
