You have interviewed Ms. Erin Roye, an IT staff member, after conducting your initial security testing of the Alexander Rocco Corporation. She informs you that the company is running an older version of Oracle’s database, Oracle 10g, for its personnel database. You decide to research whether Oracle 10g has any known vulnerabilities that you can include in your report to Ms. Roye. You don’t know whether Ms. Roye has installed any patches or software fixes; you simply want to create a report with general information.
Based on this information, write a memo to Ms. Roye describing any CVEs (common vulnerabilities and exposures) or CAN (candidate) documents you found related to Oracle 10g. (Hint: A search of the CVE Web site sponsored by US-CERT, https://cve.mitre.org/, can save you a lot of time.) If you do find vulnerabilities, your memo should include recommendations and be written in a way that doesn’t generate fear or uncertainty but encourages prudent decision-making.
A sample memo to Ms. Roye describing any CVEs (common vulnerabilities and exposures) or CAN (candidate) documents you found related to Oracle 10g is given below:
Hello, Ms. Roye,
I performed a CVE and CAN analysis of your continued use of Oracle 10g for your personnel and made some interesting findings.
One vulnerability that caught my eye about Oracle 10g was that it allows remote authenticated users to execute arbitrary SQL commands with elevated privileges.
I would urge you to rethink your use of this version of Oracle

Prompts user to enter feet length of fabric 1
inch_1 = int(input('length in inch : '))
Inch length of fabric 1
feet_2 = int(input('length in feets : '))
Feet length of fabric 2
inch_2 = int(input('length in inch : '))
Inch length of fabric 2
inch_sum = inch_1 + inch_2
Sum of the inches
inch_left = inch_sum%12
Remainder in inches after converting to feets
inch_to_feet = inch_sum // 12
Whole number of the converted inch sum
feet_sum = feet_1 + feet_2 + inch_left
