Format string vulnerability in the osLogMsg function in server/os/aulog.c in Network Audio System (NAS) 1.9.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via format string specifiers in unspecified vectors, related to syslog.

Weakness

The product uses a function that accepts a format string as an argument, but the format string originates from an external source.

Affected Software

Name Vendor Start Version End Version
Network_audio_system Radscan 1.9.3 (including) 1.9.3 (including)

Extended Description

When an attacker can modify an externally-controlled format string, this can lead to buffer overflows, denial of service, or data representation problems. It should be noted that in some circumstances, such as internationalization, the set of format strings is externally controlled by design. If the source of these format strings is trusted (e.g. only contained in library files that are only modifiable by the system administrator), then the external control might not itself pose a vulnerability.
