Description
Buffer overflow in Linuxconf before 1.28r4 allows local users to execute arbitrary code via a long LINUXCONF_LANG environment variable, which overflows an error string that is generated.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
