GLSA-200510-04 : Texinfo: Insecure temporary file creation
Low Nessus Plugin ID 19974
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200510-04 (Texinfo: Insecure temporary file creation)
Frank Lichtenheld has discovered that the 'sort_offline()' function in texindex insecurely creates 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 texindex is executed, this would result in the file being overwritten with the rights of the user running the application.
There is no known workaround at this time.
SolutionAll Texinfo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=sys-apps/texinfo-4.8-r1'
