Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities in Pidgin might allow for the remote execution |
| 19 |
of arbitrary code or a Denial of Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Pidgin (formerly Gaim) is an instant messaging client for a variety of |
| 25 |
instant messaging protocols. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |

| 31 |
Package / Vulnerable / Unaffected |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Multiple vulnerabilities have been discovered in Pidgin: |
| 39 |
|
| 40 |
* Veracode reported a boundary error in the "XMPP SOCKS5 bytestream |
| 41 |
server" when initiating an outgoing file transfer (CVE-2009-1373). |
| 42 |
|
| 43 |
* Ka-Hing Cheung reported a heap corruption flaw in the QQ protocol |
| 44 |
handler (CVE-2009-1374). |
| 45 |
|
| 46 |
* A memory corruption flaw in "PurpleCircBuffer" was disclosed by |
| 47 |
Josef Andrysek (CVE-2009-1375). |
| 48 |
|
| 49 |
* The previous fix for CVE-2008-2927 contains a cast from uint64 to |
| 50 |
size_t, possibly leading to an integer overflow (CVE-2009-1376, GLSA |
| 51 |
200901-13). |
| 52 |
|
| 53 |
Impact |
| 54 |
====== |
| 55 |
|
| 56 |
A remote attacker could send specially crafted messages or files using |
| 57 |
the MSN, XMPP or QQ protocols, possibly resulting in the execution of |
| 58 |
arbitrary code with the privileges of the user running the application, |
| 59 |
or a Denial of Service. NOTE: Successful exploitation might require the |
| 60 |
victim's interaction. |
| 61 |
|
| 62 |
Workaround |
| 63 |
========== |
| 64 |
|
| 65 |
There is no known workaround at this time. |
| 66 |
|
| 67 |
Resolution |
| 68 |
========== |
| 69 |
|
| 70 |
All Pidgin users should upgrade to the latest version: |
| 71 |
|
| 72 |
# emerge --sync |
| 73 |
# emerge --ask --oneshot --verbose ">=net-im/pidgin-2.5.6" |
| 74 |
|
