What is CVE-2016-20044?

PInfo version 0.6.9-5.1 is susceptible to a local buffer overflow vulnerability that can be exploited by local attackers. By providing an oversized argument to the -m parameter, attackers can manipulate the program's execution flow. This is achieved by crafting a malicious input string that contains 564 bytes of padding, followed by a return address, allowing the attacker to overwrite the instruction pointer. Successful exploitation enables execution of arbitrary shellcode with user privileges, representing a significant risk to system integrity and security.
