Gentoo Linux Security Advisory

Title: MPlayer, xine-lib: vulnerabilities in RTSP stream handling (GLSA 200405-24)
Severity: high
Exploitable: remote
Date: May 28, 2004
Bug(s): #49387
ID: 200405-24

Synopsis

Multiple vulnerabilities, including remotely exploitable buffer overflows, have been found in code common to MPlayer and the xine library.

Background

MPlayer is a movie player capable of handling multiple multimedia file formats. xine-lib is a multimedia player library used by several graphical user interfaces, including xine-ui. They both use the same code to handle Real-Time Streaming Protocol (RTSP) streams from RealNetworks servers.

Affected Packages

Package: media-video/mplayer
Vulnerable: < 1.0_pre4
Unaffected: >= 1.0_pre4
Unaffected: <= 0.92-r1
Architectures: All supported architectures

Package: media-libs/xine-lib
Vulnerable: < 1_rc4
Unaffected: >= 1_rc4
Unaffected: <= 0.9.13-r3
Architectures: All supported architectures


Description

Multiple vulnerabilities have been found and fixed in the RTSP handling code common to recent versions of these two packages. These vulnerabilities include several remotely exploitable buffer overflows.

Impact

A remote attacker, posing as a RTSP stream server, can execute arbitrary code with the rights of the user of the software playing the stream (MPlayer or any player using xine-lib). Another attacker may entice a user to use a maliciously crafted URL or playlist to achieve the same results.

Workaround

For MPlayer, there is no known workaround at this time. For xine-lib, you can delete the xineplug_inp_rtsp.so file.

Resolution

All users should upgrade to non-vulnerable versions of MPlayer and xine-lib:
