GLSA-200710-22 : TRAMP: Insecure temporary file creation

medium Nessus Plugin ID 27554

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200710-22 (TRAMP: Insecure temporary file creation)

 Stefan Monnier discovered that the tramp-make-tramp-temp-file() function creates temporary files in an insecure manner.
 Impact :

 A local attacker could create symbolic links in the directory where the temporary files are written, pointing to a valid file somewhere on the filesystem that is writable by the user running TRAMP. When TRAMP writes the temporary file, the target valid file would then be overwritten with the contents of the TRAMP temporary file.
 Workaround :

 There is no known workaround at this time.

Solution

All TRAMP users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=app-emacs/tramp-2.1.10-r2'
