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 >=3D 1.8.27-r1
Description ===========
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 =3Dapp-text/htmldoc-1.8.27-r1
References ==========
