[GLSA-200504-25] Rootkit Hunter: Insecure temporary file creation |

Rootkit Hunter: Insecure temporary file creation Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200504-25 (Rootkit Hunter: Insecure temporary file creation) 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. Impact 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. Workaround There is no known workaround at this time.
