Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
An integer underflow vulnerability in Pixman may allow a |
| 19 |
context-dependent attacker to cause Denial of Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Pixman is a pixel manipulation library. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 x11-libs/pixman < 0.32.4 >= 0.32.4 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
The trapezoid handling code in Pixman contains an integer underflow |
| 38 |
vulnerability. |
| 39 |
|
| 40 |
Impact |
| 41 |
====== |
| 42 |
|
| 43 |
A context-dependent attacker could entice a user to open a specially |
| 44 |
crafted file using an application linked against Pixman, possibly |
| 45 |
resulting in execution of arbitrary code with the privileges of the |
| 46 |
process, or a Denial of Service condition. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All Pixman users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=x11-libs/pixman-0.32.4" |
| 60 |
|
| 61 |
Packages which depend on this library may need to be recompiled. Tools |
| 62 |
such as revdep-rebuild may assist in identifying these packages. |
| 63 |
