VLC Media Player 2.x < 2.2.5.1 Multiple Vulnerabilities

critical Nessus Network Monitor Plugin ID 700122

Synopsis

The remote host contains a media application that is affected by multiple attack vectors.

Description

The remote host is running VLC 2.x prior to 2.2.5.1 and is affected by multiple vulnerabilities :

- A flaw exists in the OGG demuxer that is triggered by an incorrect memory free. This may allow a context-dependent attacker to have an unspecified impact. No further details have been provided.
- An out-of-bounds dereference issue in the flac decoder, which may allow a context-dependent attacker to have an unspecified impact. No further details have been provided.
- An out-of-bounds read flaw exists in the Subtitle decoder and demuxer that may allow a context-dependent attacker to potentially disclose memory contents.
- An out-of-bounds read flaw exists in the MPEG packetizer that may allow a context-dependent attacker to potentially disclose memory contents.
- An out-of-bounds read flaw exists in the 'ParseJSS()' function in 'modules/demux/subtitle.c' that is triggered when reading subtitle files. This may allow a context-dependent attacker to cause a crash.
- An overflow condition exists in the 'ParseJSS()' function in 'modules/demux/subtitle.c' that is triggered as a string terminator is not properly detected when reading subtitle files. This may allow a context-dependent attacker to cause a heap-based buffer overflow, potentially resulting in the execution of arbitrary code.
- An out-of-bounds read flaw exists in the 'CreateHtmlSubtitle()' function in 'modules/codec/subsdec.c' that is triggered when handling subtitle files. This may allow a context-dependent attacker to cause a crash.
- A flaw exists related to a ParseJSS null skip that is triggered during the handling of a specially crafted subtitle file that is download by the media player. This may allow a context-dependent attacker to potentially execute arbitrary code.

Solution

Upgrade to VLC Media Player 2.x version 2.2.5.1 or later.
