19 |
|

Background |
21 |
========== |
22 |
|

Adobe Reader (formerly Adobe Acrobat Reader) is a closed-source PDF |
24 |

Description |
35 |
=========== |
36 |
|
37 |
* An unspecified vulnerability can be triggered by a malformed PDF |
38 |
document, as demonstrated by 2008-HI2.pdf (CVE-2008-2549). |
39 |
|
40 |
* Peter Vreugdenhil, Dyon Balding, Will Dormann, Damian Frizza, and |
41 |
Greg MacManus reported a stack-based buffer overflow in the |
42 |
util.printf JavaScript function that incorrectly handles the format |
43 |
string argument (CVE-2008-2992). |
44 |
|
45 |
* Greg MacManus of iDefense Labs reported an array index error that |
46 |
can be leveraged for an out-of-bounds write, related to parsing of |
47 |
Type 1 fonts (CVE-2008-4812). |
48 |
|
49 |
* Javier Vicente Vallejo and Peter Vregdenhil, via Zero Day |
50 |
Initiative, reported multiple unspecified memory corruption |
51 |
vulnerabilities (CVE-2008-4813). |
52 |
|
53 |
* Thomas Garnier of SkyRecon Systems reported an unspecified |
54 |
vulnerability in a JavaScript method, related to an "input validation |
55 |
issue" (CVE-2008-4814). |
56 |
|
57 |
* Josh Bressers of Red Hat reported an untrusted search path |
58 |
vulnerability (CVE-2008-4815). |
59 |
|
60 |
* Peter Vreugdenhil reported through iDefense that the Download |
61 |
Manager can trigger a heap corruption via calls to the AcroJS |
62 |
function (CVE-2008-4817). |

|
64 |
Impact |
65 |
====== |
66 |
|
67 |
A remote attacker could entice a user to open a specially crafted PDF |
68 |
document, and local attackers could entice a user to run acroread from |
69 |
an untrusted working directory. Both might result in the execution of |
70 |
arbitrary code with the privileges of the user running the application, |
71 |
or a Denial of Service. |
72 |
|
73 |
Workaround |
74 |
========== |
75 |
|
76 |
There is no known workaround at this time. |
77 |
|
78 |
Resolution |
79 |
========== |
80 |
|
81 |
All Adobe Reader users should upgrade to the latest version: |
82 |
|
83 |
# emerge --sync |
84 |
# emerge --ask --oneshot --verbose ">=app-text/acroread-8.1.3" |
85 |
