Synopsis


Multiple vulnerabilities in MPlayer may lead to the execution of arbitrary code or a Denial of Service.

Background


MPlayer is a media player including support for a wide range of audio and video formats.

Affected packages



Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mplayer < 1.0_rc2_p28058-r1 >= 1.0_rc2_p28058-r1

Description


Multiple vulnerabilities have been reported in MPlayer:

  • A stack-based buffer overflow was found in the str_read_packet() function in libavformat/psxstr.c when processing crafted STR files that interleave audio and video sectors (CVE-2008-3162).
  • Felipe Andres Manzano reported multiple integer underflows in the demux_real_fill_buffer() function in demux_real.c when processing crafted Real Media files that cause the stream_read() function to read or write arbitrary memory (CVE-2008-3827).
  • Tobias Klein reported a stack-based buffer overflow in the demux_open_vqf() function in libmpdemux/demux_vqf.c when processing malformed TwinVQ files (CVE-2008-5616).

Impact


A remote attacker could entice a user to open a specially crafted STR, Real Media, or TwinVQ file to execute arbitrary code or cause a Denial of Service.

Workaround


There is no known workaround at this time.

Resolution


All MPlayer users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose
">=media-video/mplayer-1.0_rc2_p28058-r1 "
