CVE-2013-4256

Estado: ModificadaMedia (4.6)—

Multiple stack-based and heap-based buffer overflows in Network Audio System (NAS) 1.9.3 allow local users to cause a denial of service (crash) or possibly execute arbitrary code via the (1) display command argument to the ProcessCommandLine function in server/os/utils.c; (2) ResetHosts function in server/os/access.c; (3) open_unix_socket, (4) open_isc_local, (5) open_xsight_local, (6) open_att_local, or (7) open_att_svr4_local function in server/os/connection.c; the (8) AUDIOHOST environment variable to the CreateWellKnownSockets or (9) AmoebaTCPConnectorThread function in server/os/connection.c; or (10) unspecified vectors related to logging in the osLogMsg function in server/os/aulog.c.
