(Debian Issues Fix) mpg123 Buffer Overflow in getauthformURL() May Let Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1012029
SecurityTracker URL:  http://securitytracker.com/id/1012029
CVE Reference:   CVE-2004-0982   (Links to External Site)
Date:  Nov 1 2004
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 0.59r, pre0.59s
Description:   A buffer overflow vulnerability was reported in mpg123 in getauthformURL(). A remote user may be able to execute arbitrary code on the target user's system.

Carlos Barros reported that getauthfromURL() contains an overflow in the processing of the 'httpauth1' variable. A remote user can create a specially crafted playlist that, when processed by the target user, may execute arbitrary code on the target user's system.

A demonstration exploit URL format is provided:

http://AAAAAAAAAAAAAA...AAAAA@www.somesite.com/somefile.xxx,

It is reported that the http_open() function also contains a buffer overflow that allows a local user to execute arbitrary code.

The vendor was notified on October 10, 2004, without response.

Impact:   A remote user may be able to execute arbitrary code on the target user's system with the privileges of the target user.
Solution:   Debian has released a fix for the stable distribution (woody) in version 0.59r-13woody4 and for the unstable distribution (sid) in version 0.59r-17.

Debian Security Advisory DSA 578-1                     security@debian.org

Package        : mpg123
Vulnerability  : buffer overflow
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2004-0982

Carlos Barros has discovered a buffer overflow in the HTTP
authentication routine of mpg123, a popular (but non-free) MPEG layer
1/2/3 audio player.  If a user opened a malicious playlist or URL, an
attacker might execute arbitrary code with the rights of the calling
user.

For the stable distribution (woody) this problem has been fixed in
version 0.59r-13woody4.

For the unstable distribution (sid) this problem has been fixed in
version 0.59r-17.

We recommend that you upgrade your mpg123 package.
