Recommendation: Plan a near-term fix — a public PoC already exists.

iSelect 1.4.0-2+b1 contains a local buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying an oversized value to the -k/--key parameter. Attackers can craft a malicious argument containing a NOP sled, shellcode, and return address to overflow a 1024-byte stack buffer and gain code execution with user privileges.
