Solution Status:

CVE Reference(s):

Description


Luigi Auriemma has reported some vulnerabilities in Network Audio System, which potentially can be exploited by malicious, local users to gain escalated privileges or by malicious people to cause a DoS (Denial of Service).

1) A boundary error within "accept_att_local()" in server/os/connection.c can be exploited to cause a stack-based buffer overflow via an overly long (greater than 64 bytes) slave name in a USL connection.

Successful exploitation may allow malicious, local users to gain root privileges.

2) An input validation error within "AddResource()" in server/dia/resource.c can be exploited to cause the service to crash via a specially crafted packet with an invalid client ID.

3) An integer-overflow error within "ProcAuWriteElement()" in server/dia/audispatch.c can be exploited to cause the service to crash via a specially crafted packet with an overly large max_samples value.

4) A boundary error within "ProcAuSetElements()" in server/dia/audispatch.c can be exploited to cause the service to crash via a specially crafted packet with an overly large num_actions or numElements value.

5) An input validation error within "compileInputs()" in server/dia/auutil.c can be exploited to cause the service to crash via a specially crafted packet with an invalid element number.

6) A NULL-pointer dereference error when processing simultaneous connections can be exploited to cause the service to crash.

The vulnerabilities are reported in version 1.8a. Other versions may also be affected.


Solution:
Update to version 1.9.
