CVE-2012-1939: Buffer Overflow
First published: Tue Jun 05 2012(Updated: )
jsinfer.cpp in Mozilla Firefox ESR 10.x before 10.0.5 and Thunderbird ESR 10.x before 10.0.5 does not properly determine data types, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via crafted JavaScript code.
