+ Rootkit Hunter is a scanning tool to detect rootkits, backdoors + and local exploits on a local machine. Rootkit Hunter uses downloaded + data files to check file integrity. These files are updated via the + check_update.sh script. +

+
+ +

+ Sune Kloppenborg Jeppesen and Tavis Ormandy of the Gentoo Linux + Security Team have reported that the check_update.sh script and the + main rkhunter script insecurely creates several temporary files with + predictable filenames. +

+
+ +

+ A local attacker could create symbolic links in the temporary + files directory, pointing to a valid file somewhere on the filesystem. + When rkhunter or the check_update.sh script runs, this would result in + the file being overwritten with the rights of the user running the + utility, which could be the root user. +

+
+ +

+ There is no known workaround at this time. +

+
+ +

+ All Rootkit Hunter users should upgrade to the latest version: +

+ + # emerge --sync + # emerge --ask --oneshot --verbose ">=app-forensics/rkhunter-1.2.3-r1" +
