Description:
Steve Grubb has discovered a security issue in utempter, which potentially can be exploited by malicious, local users to perform certain actions with higher privileges on a vulnerable system.
The program doesn't exit correctly when a path to a device contains "/../", "/./", or "//". This may allow arbitrary files to be overwritten via symlink attacks, if a higher privileged program trusts information in the utmp file.
