Description

TRN 3.6-23 contains a stack buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying an oversized argument to the application. Attackers can craft a malicious command-line argument with 156 bytes of padding followed by a return address to overwrite the instruction pointer and execute shellcode with user privileges.
