What is CVE-2016-20048?

A critical security vulnerability exists in iSelect 1.4.0-2+b1 that allows local attackers to exploit a local buffer overflow. By providing an oversized value to the -k/--key parameter, attackers can manipulate the function to overflow a 1024-byte stack buffer. This exploitation could lead to the execution of arbitrary code with user privileges by crafting a payload that includes a NOP sled, shellcode, and a return address. Proper mitigation and updates are essential to address this issue and protect your system.
