(Debian Issues Fix) LinPopUp Buffer Overflow in strexpand() Lets Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1012824
SecurityTracker URL:  http://securitytracker.com/id/1012824
CVE Reference:   CVE-2004-1282   (Links to External Site)
Date:  Jan 10 2005
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 1.2.0
Description:   A vulnerability was reported in LinPopUp. A remote user can cause arbitrary code to be executed by the target user.

D. J. Bernstein reported that a remote user can send a specially crafted message to LinPopUp to trigger a buffer overflow in strexpand() in 'string.c' and execute arbitrary code. The code will run with the privileges of the LinPopUp process.

Stephen Dranger is credited with discovering this flaw.

Impact:   A remote user can execute arbitrary code on the target system with the privileges of the LinPopUp process.
Solution:   Debian has released a fix for the stable distribution (woody) in version 1.2.0-2woody1 and for the unstable distribution (sid) in version 1.2.0-7.

Debian GNU/Linux 3.0 alias woody:
