CVE-2012-1939: Mozilla: Miscellaneous memory safety hazards (rv:13.0/ rv:10.0.5) (MFSA 2012-34)

Severity: Critical

CVSS Score: 9.3

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.
