Synopsis |
16 |
======== |
17 |
|
18 |
Multiple insecure calls to the sscanf() function in HTMLDOC might |
19 |
result in the execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
HTMLDOC is a HTML indexer and HTML to PS and PDF converter. |
25 |
|
26 |
Affected packages |

Description |
35 |
=========== |
36 |
|
37 |
ANTHRAX666 reported an insecure call to the sscanf() function in the |
38 |
set_page_size() function in htmldoc/util.cxx. Nico Golde of the Debian |
39 |
Security Team found two more insecure calls in the write_type1() |
40 |
function in htmldoc/ps-pdf.cxx and the htmlLoadFontWidths() function in |
41 |
htmldoc/htmllib.cxx. |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
A remote attacker could entice a user to process a specially crafted |
47 |
HTML file using htmldoc, possibly resulting in the execution of |
48 |
arbitrary code with the privileges of the user running the application. |
49 |
NOTE: Additional vectors via specially crafted AFM font metric files do |
50 |
not cross trust boundaries, as the files can only be modified by |
51 |
privileged users. |
52 |
|
53 |
Workaround |
54 |
========== |
55 |
|
56 |
There is no known workaround at this time. |
57 |
|
58 |
Resolution |
59 |
========== |
60 |
|
61 |
All HTMLDOC users should upgrade to the latest version: |
62 |
|
63 |
# emerge --sync |
64 |
# emerge --ask --oneshot --verbose =app-text/htmldoc-1.8.27-r1 |
