Gentoo: GLSA-200909-12: HTMLDOC: User-assisted execution of arbitrary code
Summary
Gentoo Linux Security Advisory GLSA 200909-12
https://security.gentoo.org/
Severity: Normal
Title: HTMLDOC: User-assisted execution of arbitrary code
Date: September 12, 2009
Bugs: #278186
ID: 200909-12
Synopsis
=======
Multiple insecure calls to the sscanf() function in HTMLDOC might
result in the execution of arbitrary code.
Background
=========
HTMLDOC is a HTML indexer and HTML to PS and PDF converter.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/htmldoc < 1.8.27-r1 >= 1.8.27-r1
==========
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.
Resolution
=========
All HTMLDOC users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose =app-text/htmldoc-1.8.27-r1
