Multiple vulnerabilities have been identified in VideoLAN VLC Media Player, which could be exploited by remote attackers to cause a denial of service or compromise a vulnerable system.

The first issue is caused by buffer overflow errors in the "ParseMicroDvd()", "ParseSSA()" and "ParseVplayer()" [modules/demux/subtitle.c] functions when handling subtitles, which could be exploited by attackers to crash a vulnerable application or execute arbitrary code.

The second vulnerability is caused by a format string error in the web interface when processing the "Connection" parameter via the "httpd_FileCallBack()" [network/httpd.c] function, which could be exploited to crash a vulnerable application or execute arbitrary code.
