+ <title>Texinfo: Insecure temporary file creation</title>
+ <synopsis>
+ Texinfo is vulnerable to symlink attacks, potentially allowing a local user
+ to overwrite arbitrary files.

+ <background>
+ <p>
+ Texinfo is the official documentation system created by the GNU
+ project.

+ <description>
+ <p>
+ Frank Lichtenheld has discovered that the "sort_offline()"
+ function in texindex insecurely creates temporary files with
+ predictable filenames.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ 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.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All Texinfo users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose &quot;&gt;=sys-apps/texinfo-4.8-r1&quot;</code>
