EXPLOIT

Buffer overflow in the DecodeAdpcmImaQT function in modules/codec/adpcm.c in VideoLAN VLC media player before 2.2.4 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted QuickTime IMA file.

• → Monitor for VLC processing QuickTime IMA (.mov) files triggering an out-of-bounds write in DecodeAdpcmImaQT (adpcm.c:595); a crafted file with an excessive channel count relative to the allocated buffer is the attack vector. ↗
• → Flag VLC media player instances running versions 2.2.1 through 2.2.3 (before 2.2.4) opening .mov / QuickTime IMA files, as these versions contain the vulnerable DecodeAdpcmImaQT code path. ↗
• → Detect crashes or abnormal termination of VLC processes shortly after opening a .mov file, which may indicate exploitation of the DecodeAdpcmImaQT buffer overflow (DoS or potential RCE). ↗

• · Exploitation difficulty is elevated due to input mangling; pure RCE exploitation is non-trivial but not ruled out. ↗
• · The vulnerability is triggered specifically by the number of audio channels in the input stream exceeding the allocated buffer size; detection logic should account for this channel-count anomaly in QuickTime IMA files. ↗
