Synopsis |
16 |
======== |
17 |
|
18 |
Poppler is vulnerable to an integer overflow and a stack overflow. |
19 |
|
20 |
Background |
21 |
========== |
22 |
|
23 |
Poppler is a cross-platform PDF rendering library originally based on |
24 |
Xpdf. |

Affected packages |

Description |
35 |
=========== |
36 |
|
37 |
Poppler and Xpdf are vulnerable to an integer overflow in the |
38 |
StreamPredictor::StreamPredictor function, and a stack overflow in the |
39 |
StreamPredictor::getNextLine function. The original vulnerability was |
40 |
discovered by Maurycy Prodeus. Note: Gentoo's version of Xpdf is |
41 |
patched to use the Poppler library, so the update to Poppler will also |
42 |
fix Xpdf. |
43 |
|
44 |
Impact |
45 |
====== |
46 |
|
47 |
By enticing a user to view a specially crafted program with a |
48 |
Poppler-based PDF viewer such as Gentoo's Xpdf, Epdfview, or Evince, a |
49 |
remote attacker could cause an overflow, potentially resulting in the |
50 |
execution of arbitrary code with the privileges of the user running the |
51 |
application. |
52 |
|
53 |
Workaround |
54 |
========== |
55 |
|
56 |
There is no known workaround at this time. |
57 |
|
58 |
Resolution |
59 |
========== |
60 |
|
61 |
All Poppler users should upgrade to the latest version of Poppler: |
62 |
|
63 |
# emerge --sync |
64 |
# emerge --ask --oneshot --verbose ">=app-text/poppler-0.5.4-r2" |
65 |
