Title: Multiple Vendor CDE dtspcd Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
CDE is a Motif-based graphical user environment for UNIX systems. It is shipped with a number of commercial systems.
A buffer-overflow vulnerability in the 'dtspcd' component may allow a remote attacker to gain administrative privileges on the affected host. The overflow is believed to be in the libDtSvc library, which used by the 'Subprocess Control Service'. The overflow is exploitable through the 'dtspcd' service, a server utility that facilitates remote invocation of CDE utilities and commands. The 'dtspcd' service listens on TCP port 6112, runs with root privileges, and is enabled by default (through 'inetd') on many systems.
The vulnerability reportedly occurs because of a lack of validation of remotely supplied data. Remote clients can supply a length value within a 'dtspcd' request that causes an overflow when processing the request data. Attackers may be able to change the execution flow of the server by replacing critical values on the stack such as a function return address with arbitrary data.
The attacker could gain local access to a vulnerable system with administrative privileges. It is currently unknown whether this vulnerability affects other CDE applications.
