Description:
The CDE dtprintinfo program is vulnerable to a buffer overflow
condition that allows a local attacker to gain root access. The
problem occurs due to insufficient bounds checking in the Volume
search field from the Help section. An attacker can insert a specially
crafted string for the search parameter and gain root privileges.

In the dtprintinfo Help, an Index search function permits querying by
keyword. If a string of appropriate length is inserted into the 
'Entries with' field and a single Help Volume is selected for the
search, an exploitable buffer overflow will occur.

Upgrade with the following patches.
