GLSA-200602-14 : noweb: Insecure temporary file creation
Low Nessus Plugin ID 20980
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200602-14 (noweb: Insecure temporary file creation)
Javier Fernandez-Sanguino has discovered that the lib/toascii.nw and shell/roff.mm scripts insecurely create temporary files with predictable filenames.
A local attacker could create symbolic links in the temporary file directory, pointing to a valid file somewhere on the filesystem. When an affected script is called, this would result in the file being overwritten with the rights of the user running the script.
There is no known workaround at this time.
SolutionAll noweb users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-text/noweb-2.9-r5'
