[GLSA]

Gentoo Linux Security Advisory

Title: Multi-Threaded DAAP Daemon: Multiple vulnerabilities (GLSA 200712-18)
Severity: high
Exploitable: remote
Date: December 29, 2007
Bug(s): #200110
ID: 200712-18

Synopsis


Multiple vulnerabilities in the web server in the Multi-Threaded DAAP
Daemon may lead to the remote execution of arbitrary code.


Background


Multi-Threaded DAAP Daemon (mt-daapd), also known as the Firefly Media
Server, is a software to serve digital music to the Roku Soundbridge
and Apple's iTunes.


Affected Packages

Package: media-sound/mt-daapd
Vulnerable: < 0.2.4.1
Unaffected: >= 0.2.4.1
Architectures: All supported architectures


Description


nnp discovered multiple vulnerabilities in the XML-RPC handler in the
file webserver.c. The ws_addarg() function contains a format string
vulnerability, as it does not properly sanitize username and password
data from the "Authorization: Basic" HTTP header line (CVE-2007-5825).
The ws_decodepassword() and ws_getheaders() functions do not correctly
handle empty Authorization header lines, or header lines without a ':'
character, leading to NULL pointer dereferences (CVE-2007-5824).


Impact


A remote attacker could send specially crafted HTTP requests to the web
server in the Multi-Threaded DAAP Daemon, possibly leading to the
execution of arbitrary code with the privileges of the user running the
web server or a Denial of Service.


Workaround


There is no known workaround at this time.


Resolution


All Multi-Threaded DAAP Daemon users should upgrade to the latest
version:
