Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Sylpheed and Sylpheed-Claws contain a buffer overflow vulnerability |
| 19 |
which may lead to the execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Sylpheed is a lightweight email client and newsreader. Sylpheed-Claws |
| 25 |
is a 'bleeding edge' version of Sylpheed. They both support the import |
| 26 |
of address books in LDIF (Lightweight Directory Interchange Format). |

Description |
| 41 |
=========== |
| 42 |
|
| 43 |
Colin Leroy reported buffer overflow vulnerabilities in Sylpheed and |
| 44 |
Sylpheed-Claws. The LDIF importer uses a fixed length buffer to store |
| 45 |
data of variable length. Two similar problems exist also in the Mutt |
| 46 |
and Pine addressbook importers of Sylpheed-Claws. |
| 47 |
|
| 48 |
Impact |
| 49 |
====== |
| 50 |
|
| 51 |
By convincing a user to import a specially-crafted LDIF file into the |
| 52 |
address book, a remote attacker could cause the program to crash, |
| 53 |
potentially allowing the execution of arbitrary code with the |
| 54 |
privileges of the user running the software. |
| 55 |
|
| 56 |
Workaround |
| 57 |
========== |
| 58 |
|
| 59 |
There is no known workaround at this time. |
| 60 |
|
| 61 |
Resolution |
| 62 |
========== |
| 63 |
|
| 64 |
All Sylpheed users should upgrade to the latest version: |
| 65 |
|
| 66 |
# emerge --sync |
| 67 |
# emerge --ask --oneshot --verbose ">=mail-client/sylpheed-2.0.4" |
| 68 |
|
| 69 |
All Sylpheed-Claws users should upgrade to the latest version: |
| 70 |
|
| 71 |
# emerge --sync |
| 72 |
# emerge --ask --oneshot --verbose |
| 73 |
">=mail-client/sylpheed-claws-1.0.5-r1" |
| 74 |
|
