[GLSA-200509-21] Hylafax: Insecure temporary file creation in xferfaxstats script

Vulnerability Assessment Summary
Hylafax: Insecure temporary file creation in xferfaxstats script

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200509-21
(Hylafax: Insecure temporary file creation in xferfaxstats script)

Javier Fernandez-Sanguino has discovered that xferfaxstats cron
script supplied by Hylafax insecurely creates temporary files with
predictable filenames.

Impact

A local attacker could create symbolic links in the temporary file
directory, pointing to a valid file somewhere on the filesystem. When
the xferfaxstats script of Hylafax is executed, this would result in
the file being overwritten with the rights of the user running the
script, which typically is the root user.

Workaround

There is no known workaround at this time.

# emerge --sync
# emerge --ask --oneshot --verbose net-misc/hylafax
