GLSA-200909-12 : HTMLDOC: User-assisted execution of arbitrary code

This script is Copyright (C) 2009-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200909-12
(HTMLDOC: User-assisted execution of arbitrary code)

ANTHRAX666 reported an insecure call to the sscanf() function in the
set_page_size() function in htmldoc/util.cxx. Nico Golde of the Debian
Security Team found two more insecure calls in the write_type1()
function in htmldoc/ps-pdf.cxx and the htmlLoadFontWidths() function in
htmldoc/htmllib.cxx.

Impact :

A remote attacker could entice a user to process a specially crafted
HTML file using htmldoc, possibly resulting in the execution of
arbitrary code with the privileges of the user running the application.
NOTE: Additional vectors via specially crafted AFM font metric files do
not cross trust boundaries, as the files can only be modified by
privileged users.

Workaround :

There is no known workaround at this time.

Solution :

All HTMLDOC users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-text/htmldoc-1.8.27-r1'

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
