GLSA-200510-02 : Berkeley MPEG Tools: Multiple insecure temporary files
Low Nessus Plugin ID 19822
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200510-02 (Berkeley MPEG Tools: Multiple insecure temporary files)
Mike Frysinger of the Gentoo Security Team discovered that mpeg_encode and the conversion utilities were creating temporary files with predictable or fixed filenames. The 'test' make target of the MPEG Tools also relied on several temporary files created insecurely.
A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem.
When the utilities are executed (or 'make test' is run), this would result in the file being overwritten with the rights of the user running the command.
There is no known workaround at this time.
SolutionAll Berkeley MPEG Tools users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-video/mpeg-tools-1.5b-r2'
