Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
The cookie manager component in kdelibs contains a vulnerability |
| 19 |
allowing an attacker to potentially gain access to a user's session on |
| 20 |
a legitimate web server. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
KDE is a widely-used desktop environment based on the Qt toolkit. |
| 26 |
kcookiejar in kdelibs is responsible for storing and managing HTTP |
| 27 |
cookies. Konqueror uses kcookiejar for storing and managing cookies. |
| 28 |
|
| 29 |
Affected packages |

================= |

------------------------------------------------------------------- |
| 33 |
Package / Vulnerable / Unaffected |

Description |
| 38 |
=========== |
| 39 |
|
| 40 |
kcookiejar contains a vulnerability which may allow a malicious website |
| 41 |
to set cookies for other websites under the same second-level domain. |
| 42 |
|
| 43 |
This vulnerability applies to country-specific secondary top level |
| 44 |
domains that use more than 2 characters in the secondary part of the |
| 45 |
domain name, and that use a secondary part other than com, net, mil, |
| 46 |
org, gov, edu or int. However, certain popular domains, such as co.uk, |
| 47 |
are not affected. |
| 48 |
|
| 49 |
Impact |
| 50 |
====== |
| 51 |
|
| 52 |
Users visiting a malicious website using the Konqueror browser may have |
| 53 |
a session cookie set for them by that site. Later, when the user visits |
| 54 |
another website under the same domain, the attacker's session cookie |
| 55 |
will be used instead of the cookie issued by the legitimate site. |
| 56 |
Depending on the design of the legitimate site, this may allow an |
| 57 |
attacker to gain access to the user's session. For further explanation |
| 58 |
on this type of attack, see the paper titled "Session Fixation |
| 59 |
Vulnerability in Web-based Applications" (reference 2). |
| 60 |
|
| 61 |
Workaround |
| 62 |
========== |
| 63 |
|
| 64 |
There is no known workaround at this time. All users are encouraged to |
| 65 |
upgrade to the latest available version of kdelibs. |
| 66 |
|
| 67 |
Resolution |
| 68 |
========== |
| 69 |
|
| 70 |
All kdelibs users should upgrade to the latest version: |
| 71 |
|
| 72 |
# emerge sync |
| 73 |
|
| 74 |
# emerge -pv ">=kde-base/kdelibs-3.2.3-r2" |
| 75 |
# emerge ">=kde-base/kdelibs-3.2.3-r2" |
| 76 |
