CVE-2016-1946: Buffer Overflow
First published: Sun Jan 31 2016(Updated: )
The MoofParser::Metadata function in binding/MoofParser.cpp in libstagefright in Mozilla Firefox before 44.0 does not limit the size of read operations, which might allow remote attackers to cause a denial of service (integer overflow and buffer overflow) or possibly have unspecified other impact via crafted metadata.
