Title: Rootkit Hunter Local Insecure Temporary File Creation Vulnerability
Severity: MODERATE
Description:
Rootkit scanner is a security tool designed to identify potentially malicious tools on a computer. It is freely available for most UNIX and Unix variant platforms.
A local insecure file creation vulnerability affects Rootkit Hunter. This issue is due to a design error that causes a file to be insecurely opened or created and subsequently written to.
The problem presents itself when the 'check_update.sh' and main rkhunter script create numerous temporary files insecurely; temporary files with predictable file names are created in insecure directories by default.
An attacker may leverage this issue to corrupt arbitrary files with the privileges of an unsuspecting user that activates the affected application.
