Yderligere oplysninger:

Flere sårbarheder er opdaget i nas, Network Audio System.

CVE-2007-1543
Et stakbaseret bufferoverløb i funktionen accept_att_local i server/os/connection.c i nas gjorde det muligt for fjernangribere at udføre vilkårlig kode gennem et langt sti-slavenavn i en USL-socketforbindelse.
CVE-2007-1544
Et heltalsoverløb i funktionen ProcAuWriteElement i server/dia/audispatch.c gjorde det muligt for fjernangribere at forårsage et lammelsesangreb (denial of service, nedbrud) samt muligvis udførelse af vilkårlig kode gennem en lang max_samples-værdi.
CVE-2007-1545
Funktionen AddResource i server/dia/resource.c gjorde det muligt for fjernangribere at forårsage et lammelsesangreb (server-nedbrud) gennem en ikke-eksisterende klient-id.
CVE-2007-1546
Arrayindeksfejl gjorde det muligt for fjernangribere at forårsage et lammelsesangreb (nedbrud) gennem (1) store num_action-værdier i funktionen ProcAuSetElements i server/dia/audispatch.c eller (2) et stort inputNum-parameter til funktionen compileInputs i server/dia/auutil.c.
CVE-2007-1547
Funktionen ReadRequestFromClient i server/os/io.c gjorde det muligt for fjernangribere at forårsage lammelsesangreb (nedbrud) gennem mange samtidige forbindelser, hvilket udløste en NULL-pointerdereference.

I den stabile distribution (sarge), er disse problemer rettet i version 1.7-2sarge1.

I den kommende stabile distribution (etch) og i den ustabile distribution (sid) er disse problemer rettet i version 1.8-4.

Vi anbefaler at du opgraderer din nas-pakke.
