Synopsis |
16 |
======== |
17 |
|
18 |
Multiple integer overflows in the Ghostscript ICC library might allow |
19 |
for user-assisted execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Ghostscript is an interpreter for the PostScript language and the |
25 |
Portable Document Format (PDF). |

NOTE: Certain packages are still vulnerable. Users should migrate |
38 |
to another package if one is available or wait for the |
39 |
existing packages to be marked stable by their |
40 |
architecture maintainers. |

Description |
46 |
=========== |
47 |
|
48 |
Jan Lieskovsky from the Red Hat Security Response Team discovered the |
49 |
following vulnerabilities in Ghostscript's ICC Library: |
50 |
|
51 |
* Multiple integer overflows (CVE-2009-0583). |
52 |
|
53 |
* Multiple insufficient bounds checks on certain variable sizes |
54 |
(CVE-2009-0584). |
55 |
|
56 |
Impact |
57 |
====== |
58 |
|
59 |
A remote attacker could entice a user to open a specially crafted |
60 |
PostScript file containing images and a malicious ICC profile, possibly |
61 |
resulting in the execution of arbitrary code with the privileges of the |
62 |
user running the application. |
63 |
|
64 |
Workaround |
65 |
========== |
66 |
|
67 |
There is no known workaround at this time. |
68 |
|
69 |
Resolution |
70 |
========== |
71 |
|
72 |
All GPL Ghostscript users should upgrade to the latest version: |
73 |
|
74 |
# emerge --sync |
75 |
# emerge --ask --oneshot --verbose ">=app-text/ghostscript-gpl-8.64-r2" |
76 |
|
77 |
All GNU Ghostscript users should upgrade to the latest version: |
78 |
|
79 |
# emerge --sync |
80 |
# emerge --ask --oneshot --verbose ">=app-text/ghostscript-gnu-8.62.0" |
81 |
|
82 |
We recommend that users unmerge ESP Ghostscript and use GPL or GNU |
83 |
Ghostscript instead: |
84 |
|
85 |
# emerge --unmerge "app-text/ghostscript-esp" |
86 |
|
87 |
For installation instructions, see above. |
