The remote host is running VLC 2.x prior to 2.0.2 and is affected by multiple vulnerabilities :

 - An invalid pointer dereference flaw exists in the 3GP file format parser. With a specially crafted 3GP file, a context-dependent attacker can potentially execute arbitrary code.
 - The libpng library used by VLC contains an out-of-bounds read flaw in the 'png_convert_to_rfc1123()' function in 'png.c' that may allow a context-dependent attacker to crash an application linked against the library or disclose memory contents.
 - The libEBML library used by VLC contains a use-after-free error in the 'EblMaster::Read()' function in 'EbmlMaster.cpp' that is triggered when handling deeply nested elements with an infinite size. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
 - The libEBML library used by VLC contains an out-of-bounds read condition in the 'UTFstring::UpdateFromUTF8()' function in 'EbmlUnicodeString.cpp' that is triggered when reading UTF-8 strings. This may allow a context-dependent attacker to crash an application linked against the library or potentially disclose memory contents.
 - The libpng library contains overflow conditions in the 'png_set_PLTE()' function in 'pngset.c' and 'png_get_PLTE()' function in 'pngget.c' that are triggered when handling bit depths less than 8. With a specially crafted PNG image, a context-dependent attacker can cause a buffer overflow, crashing an application linked against the library or potentially execute arbtirary code.
 - A flaw exists that allows a cross-site scripting (XSS) attack. This flaw exists because the web interface does not validate files' title metadata before returning it to users. This may allow a context-dependent attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.
 - A flaw exists that is triggered as user-supplied input is not properly validated when handling a specially crafted MP4 file. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - An unspecified double-free flaw exists in the ADPCM decoder, which may allow an attacker to have an unspecified impact.
 - Multiple unspecified double-frees, integer overflows, infinite loops, read overflows, invalid frees, and division-by-zero flaws exist. No further details have been provided by the vendor.
 - A flaw exists that allows a cross-site scripting (XSS) attack. This flaw exists because the HTTP interface does not validate input before returning it to users. This may allow a remote attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.
 - An off-by-one overflow condition exists in the RealRtsp module. The issue is triggered as user-supplied input is not properly validated. This may allow a context-dependent attacker to cause a buffer overflow, resulting in an unspecified impact.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - VideoLAN VLC media player 2.2.1 allows remote attackers to cause a denial of service (crash) and possibly
    execute arbitrary code via a crafted 3GP file, which triggers the freeing of arbitrary pointers.
    (CVE-2015-5949)

A denial of service (DoS) vulnerability exists in VLC media player before 2.2.2. Allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted 3GP file, which triggers the freeing of arbitrary pointers.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

This update for vlc fixes the following issues :

  - CVE-2015-5949: Remote attackers could have caused a     denial of service (crash) and possibly execute arbitrary     code via a crafted 3GP file (boo#965227)

The remote host is affected by the vulnerability described in GLSA-201603-08 (VLC: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in VLC. Please review the       CVE identifiers referenced below for details.
  Impact :

    Remote attackers could possibly execute arbitrary code or cause Denial       of Service.
  Workaround :

    There is no known work around at this time.

Loren Maggiore of Trail of Bits discovered that the 3GP parser of VLC, a multimedia player and streamer, could dereference an arbitrary pointer due to insufficient restrictions on a writable buffer. This could allow remote attackers to execute arbitrary code via crafted 3GP files.

oCERT reports :

The stable VLC version suffers from an arbitrary pointer dereference vulnerability.

The vulnerability affects the 3GP file format parser, insufficient restrictions on a writable buffer can be exploited to execute arbitrary code via the heap memory. A specific 3GP file can be crafted to trigger the vulnerability.
