Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Evolution is vulnerable to format string vulnerabilities which may |
| 19 |
result in remote execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Evolution is a GNOME groupware application. |
| 25 |
|
| 26 |
Affected packages |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Ulf Harnhammar discovered that Evolution is vulnerable to format string |
| 38 |
bugs when viewing attached vCards and when displaying contact |
| 39 |
information from remote LDAP servers or task list data from remote |
| 40 |
servers (CAN-2005-2549). He also discovered that Evolution fails to |
| 41 |
handle special calendar entries if the user switches to the Calendars |
| 42 |
tab (CAN-2005-2550). |
| 43 |
|
| 44 |
Impact |
| 45 |
====== |
| 46 |
|
| 47 |
An attacker could attach specially crafted vCards to emails or setup |
| 48 |
malicious LDAP servers or calendar entries which would trigger the |
| 49 |
format string vulnerabilities when viewed or accessed from Evolution. |
| 50 |
This could potentially result in the execution of arbitrary code with |
| 51 |
the rights of the user running Evolution. |
| 52 |
|
| 53 |
Workaround |
| 54 |
========== |
| 55 |
|
| 56 |
There is no known workaround at this time. |
| 57 |
|
| 58 |
Resolution |
| 59 |
========== |
| 60 |
|
| 61 |
All Evolution users should upgrade to the latest version: |
| 62 |
|
| 63 |
# emerge --sync |
| 64 |
# emerge --ask --oneshot --verbose ">=mail-client/evolution-2.2.3-r3" |
| 65 |
