Description |
44 |
=========== |
45 |
|
46 |
Chris Evans (Google Security) discovered a stack-based buffer overflow |
47 |
within the zseticcspace() function in the file zicc.c when processing a |
48 |
PostScript file containing a long "Range" array in a .seticcscpate |
49 |
operator. |
50 |
|
51 |
Impact |
52 |
====== |
53 |
|
54 |
A remote attacker could exploit this vulnerability by enticing a user |
55 |
to open a specially crafted PostScript file, which could possibly lead |
56 |
to the execution of arbitrary code or a Denial of Service. |
57 |
|
58 |
Workaround |
59 |
========== |
60 |
|
61 |
There is no known workaround at this time. |
62 |
|
63 |
Resolution |
64 |
