Title: Groff Pre-Processor Buffer Overflow Vulnerability
Severity: HIGH
Description:
groff is a document formatting utility used on many Linux systems.
groff is normally invoked by LPRng (or another printer spooler) when a document needs to be formatted.
An exploitable buffer overflow exists in the groff pre-processor. An attacker may be able to overrun the buffer, overwriting locations in memory to cause arbitrary attacker-supplied instructions to be executed. This is due to insufficient bounds checking. Attacker-supplied code will be executed with the privileges of the lp user.
This issue is remotely exploitable in the case that the line printer daemon (lpd) is running and may be accessed by remote hosts. Successful exploitation would allow an attacker to gain local access to a host running the vulnerable software, with the privileges of the lp user.
