Title: Sun Solaris 'ypbind' Unspecified Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
'ypbind' is an RPC service that allows Network Information Service (NIS) clients to locate NIS services on a network.
It is reported that 'ypbind' is susceptible to an unspecified remote buffer overflow vulnerability. This vulnerability exists due to insufficient boundary checks performed on user-supplied data.
'ypbind' runs with superuser privileges, therefore, remote code execution as the superuser is possible. It is also likely that a system-wide denial of service condition could be created by crashing the 'ypbind' process.
Due to a lack of details, further information is not available at the moment. This BID will be updated as more information becomes available.
Versions of Solaris prior to Solaris 8 01/01, or Solaris 8 Maintenance Update 3 are reported vulnerable.
