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

critical Nessus Plugin ID 40959

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'
