Debian DSA-1273-1 : nas - several vulnerabilities

critical Nessus Plugin ID 24921

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities have been discovered in nas, the Network Audio System.

- CVE-2007-1543 A stack-based buffer overflow in the accept_att_local function in server/os/connection.c in nas allows remote attackers to execute arbitrary code via a long path slave name in a USL socket connection.

- CVE-2007-1544 An integer overflow in the ProcAuWriteElement function in server/dia/audispatch.c allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large max_samples value.

- CVE-2007-1545 The AddResource function in server/dia/resource.c allows remote attackers to cause a denial of service (server crash) via a nonexistent client ID.

- CVE-2007-1546 An array index error allows remote attackers to cause a denial of service (crash) via (1) large num_action values in the ProcAuSetElements function in server/dia/audispatch.c or (2) a large inputNum parameter to the compileInputs function in server/dia/auutil.c.

- CVE-2007-1547 The ReadRequestFromClient function in server/os/io.c allows remote attackers to cause a denial of service (crash) via multiple simultaneous connections, which triggers a NULL pointer dereference.

Solution

Upgrade the nas package.

For the stable distribution (sarge), these problems have been fixed in version 1.7-2sarge1.

For the upcoming stable distribution (etch) and the unstable distribution (sid) these problems have been fixed in version 1.8-4.
