Vulnerability Details:
Embedding Javascript code within a SVG file leads to script execution when 
opening that attachment. Malicious code may be transported by E-Mail or file 
uploads by other users. Inline images within mail are not affected.

Risk:
Malicious script code can be executed within a users context. This can lead to 
session hijacking or triggering unwanted actions via the web interface (sending 
mail, deleting data etc.)

Solution:
Users should update to the latest available patch releases. Users should avoid 
opening E-Mail attachments from untrusted sources.



Internal reference: 29315 (Bug ID)
Vulnerability type: CWE-200 (Information Exposure)
Vulnerable version: prior to 7.4.0
Vulnerable component: backend
Fixed version: 7.2.2-rev25, 7.4.0-rev14
Report confidence: Confirmed
Solution status: Fixed by Vendor
Vendor notification: 2013-10-16
Solution date: 2013-10-21
Public disclosure: 2013-11-06
CVE reference: CVE-2013-6241
CVSSv2: 6.2 
(AV:N/AC:L/Au:S/C:P/I:N/A:N/E:POC/RL:U/RC:C/CDP:MH/TD:H/CR:ND/IR:ND/AR:ND)

Vulnerability Details:
Information of contacts (birthday, surname, firstname, displayname) are exposed 
through the “Birthday” widget using the api/contacts?action=birthdays call. 
This affects contact information where the birthday date is at the next year 
and the contact information is stored at the same database schema. 
Additionally, this is limited to contacts of users that share the same user-id 
within different contexts. If birthdays are due at the following year, the 
decision tree uses an incorrect SQL statement that bypasses context isolation.

Risk:
Users from different contexts may gain unauthorized access to a subset of 
contact data.


Solution:
Users should update to the latest available patch releases.
