GLSA-200407-01 : Esearch: Insecure temp file handling
High Nessus Plugin ID 14534
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200407-01 (Esearch: Insecure temp file handling)
The eupdatedb utility uses a temporary file (/tmp/esearchdb.py.tmp) to indicate that the eupdatedb process is running. When run, eupdatedb checks to see if this file exists, but it does not check to see if it is a broken symlink. In the event that the file is a broken symlink, the script will create the file pointed to by the symlink, instead of printing an error and exiting.
An attacker could create a symlink from /tmp/esearchdb.py.tmp to a nonexistent file (such as /etc/nologin), and the file will be created the next time esearchdb is run.
There is no known workaround at this time. All users should upgrade to the latest available version of esearch.
SolutionAll users should upgrade to the latest available version of esearch, as follows:
# emerge sync # emerge -pv '>=app-portage/esearch-0.6.2' # emerge '>=app-portage/esearch-0.6.2'
