plugins\codec\libflac_plugin.dll in VideoLAN VLC media player 2.2.4 allows remote attackers to cause a denial of service (heap corruption and application crash) or possibly have unspecified other impact via a crafted FLAC file.

Several vulnerabilities have been found in VLC, the VideoLAN project's media player. Processing malformed media files could lead to denial of service and potentially the execution of arbitrary code.

This update for vlc to version 2.2.6 fixes several issues.

This security issue was fixed :

  - CVE-2017-9300: Heap corruption allowed remote attackers     to cause a denial of service or possibly have     unspecified other impact via a crafted FLAC file     (bsc#1041907).

These non-security issues were fixed :

  - Stop depending on libkde4-devel: It's only used to find     the install path for kde4, but configure falls back to     the correct default for openSUSE anyway (boo#1057736).

  - Disable vnc access module

For the various other fixes introduced by 2.2.6 please see the changelog.

The version of VLC media player installed on the remote host is prior to 2.2.5. It is, therefore, affected by the multiple vulnerabilities :

  - A denial of service vulnerability exists within file plugins\audio_filter\libmpgatofixed32_plugin.dll when     parsing media files due to improper validation of user-supplied input. An unauthenticated, remote attacker     can exploit this, via a specially crafted file, to crash the application. (CVE-2017-9301)

  - A flaw exists, related to a ParseJSS null skip, when handling specially crafted subtitle files downloaded by     the media player. An unauthenticated, remote attacker can exploit this, via a specially crafted file, to     execute arbitrary code.

  - A heap-based buffer overflow condition exists due to improper validation of user-supplied input. An unauthenticated,     remote attacker can exploit this, via a specially crafted AVI file, to execute arbitrary code.

  - A memory corruption issue exists when handling LPCM in VOB files. An unauthenticated, remote attacker can     exploit this, via a specially crafted file, to execute arbitrary code.
    
  - An exploitable vulnerability exists in plugins\codec\libflac_plugin.dll, allows remote attackers to cause     denial of service (heap corruption and application crash) or possibly have unspecified other impact via a crafted     FLAC file. (CVE-2017-9300). 

  - An exploitable Heap out-of-bound read vulnerability exists in ParseJSS of VideoLan VLC. This is due to missing check of     string termination allows attackers to read data beyond allocated memory and potentially crash the process via a crafted     subtitles file. (CVE-2017-8313).

  - An exploitable heap based buffer overflow vulnerability exists in ParseJSS of VideoLan VLC. This is due to skipping NULL     terminator in an input string allows attackers to execute arbitrary code via a crafted subtitles file. (CVE-2017-8311).

  - An exploitable Heap out-of-bound read vulnerability exists in CreateHtmlSubtitle of VideoLan VLC. This is due to missing     check of string termination allows attackers to read data beyond allocated memory and potentially crash the process     (causing a denial of service) via a crafted subtitles file. (CVE-2017-8310).
