Version Information

Release Date February 27, 2007

Impact normal
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)
media-video/mplayer < 1.0_rc1-r2 >= 1.0_rc1-r2 All supported architectures

Related bugreports: #159727


A buffer overflow was found in MPlayer's RTSP plugin that could lead to a Denial of Service or arbitrary code execution.

2.  Impact Information


MPlayer is a media player capable of playing multiple media formats.


When checking for matching asm rules in the asmrp.c code, the results are stored in a fixed-size array without boundary checks which may allow a buffer overflow.


An attacker can entice a user to connect to a manipulated RTSP server resulting in a Denial of Service and possibly execution of arbitrary code.

3.  Resolution Information


There is no known workaround at this time.


All MPlayer users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0_rc1-r2"
