Vulnerability Assessment Details
Berkeley MPEG Tools: Multiple insecure temporary files
Detailed Explanation for this Vulnerability Assessment
The 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.
All Berkeley MPEG Tools users should upgrade to the latest
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/mpeg-tools-1.5b-r2"
Network Security Threat Level: Medium
