[GLSA-200603-03] MPlayer: Multiple integer overflows |
||
MPlayer: Multiple integer overflows Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200603-03 (MPlayer: Multiple integer overflows) MPlayer makes use of the FFmpeg library, which is vulnerable to a heap overflow in the avcodec_default_get_buffer() function discovered by Simon Kilvington (see GLSA 200601-06). Furthermore, AFI Security Research discovered two integer overflows in ASF file format decoding, in the new_demux_packet() function from libmpdemux/demuxer.h and the demux_asf_read_packet() function from libmpdemux/demux_asf.c. Impact A possible hacker could craft a malicious media file which, when opened using MPlayer, would lead to a heap-based buffer overflow. This could result in the execution of arbitrary code with the permissions of the user running MPlayer. Workaround There is no known workaround at this time.
