Security Advisory 1601

Summary           : Buffer Overflow in Processing QuickTime IMA Files
Date              : June 2016
Affected versions : VLC media player 2.2.3 and earlier
ID                : VideoLAN-SA-1601
CVE reference     : CVE-2016-5108

Details

A remote user can create a specially crafted QuickTime IMA file that, when loaded by the target user, will trigger a buffer overflow in DecodeAdpcmImaQT() in 'modules/codec/adpcm.c'.

Impact

If successful, a malicious third party could trigger either a crash of VLC or an arbitratry code execution with the privileges of the target user.

Threat mitigation

Exploitation of those issues requires the user to explicitly open a specially crafted file or stream.

ASLR and DEP help reduce exposure, but may be bypassed.

Workarounds

The user should refrain from opening files from untrusted third parties or accessing untrusted remote sites (or disable the VLC browser plugins), until the patch is applied.

Solution

VLC media player 2.2.4 addresses the issue.
