SecurityTracker URL:  http://securitytracker.com/id/1011806
CVE Reference:   CVE-2001-1413   (Links to External Site)

Version(s): 4.2.4 and prior versions
Description:   A vulnerability was reported in ncompress. A remote user may be able to execute arbitrary code.

In November 2001, Pavel Kankovsky reported that ncompress contains a stack-based buffer overflow. A local user can supply a specially crafted filename longer than 1023 characters to trigger the buffer overflow and potentially execute arbitrary code.

If a network-based application invokes ncompress (such as an FTP server), then a remote user may be able to exploit this flaw.

Impact:   A remote user may be able to execute arbitrary code on the target system.
Solution:   No upstream solution was available at the time of this entry.
Cause:   Boundary error
Underlying OS:  Linux (Any), UNIX (Any)
