Linuxconf LINUXCONF_LANG environment variable buffer overflow
|linuxconf-linuxconflang-env-bo (9980)||High Risk|
Linuxconf is vulnerable to a buffer overflow. By passing 964 or more bytes of data to the LINUXCONF_LANG environment variable, a local attacker could overflow a buffer and execute arbitrary code on the system with root privileges.
Upgrade to the latest version of Linuxconf (1.29r4 or later), available from the Linuxconf Web page. See References.
As a workaround, $ chmod u-s /bin/linuxconf
