UnknownEPSS 3.74%

Last modified

CVE-2015-2712 is a vulnerability of currently unknown severity. The asm.js implementation in Mozilla Firefox before 38.0 does not properly determine heap lengths during identification of cases in which bounds checking may be safely skipped, which allows remote attackers to trigger out-of-bounds write operations and possibly execute arbitrary code, or trigger out-of-bounds read operations and possibly obtain sensitive information from process memory, via crafted JavaScript.. EPSS estimates a 3.74% chance of exploitation in the next 30 days.
