CVE Descriptions

The ASF_ReadObject_file_properties function in modules/demux/asf/libasf.c in the ASF Demuxer in VideoLAN VLC Media Player before 2.1.3 allows remote attackers to cause a denial of service (divide-by-zero error and crash) via a zero minimum and maximum data packet size in an ASF file.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

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.

EPSS Percentile

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.
