The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Affected versions of this package are vulnerable to Off-by-one Error in the calculation of the mask to the pshufb
instruction.
The vulnerability exists due to a bug on x86_64
platforms for the WebAssembly i8x16.select
instruction, which will produce the wrong results when the same operand is provided to the instruction and some of the selected indices are greater than 16.
If upgrading is not an option for you at this time, you can avoid this miscompilation by disabling the Wasm simd
proposal
config.wasm_simd(false);
Additionally, the bug is only present on x86_64 hosts. Other platforms such as AArch64
and s390x
are not affected.
