Description:
A vulnerability was reported in Sylpheed. A remote user may be able to execute arbitrary code on the target system in certain cases.
A remote user can send a message with specially crafted headers to the target user. Then, when the target user replies to the affected message, a buffer overflow may occur. It may be possible to execute arbitrary code, however, the report did not confirm this.
Certain headers containing non-ASCII characters can trigger the overflow.
|
Impact:
A remote user may be able to execute arbitrary code on the target user's system.
[Editor's note: The report did not confirm code execution.]
|
Solution:
Gentoo has issued a fix and indicates that all Sylpheed users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/sylpheed-1.0.3"
All Sylpheed-claws users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/sylpheed-claws-1.0.3"

Synopsis
========
Sylpheed and Sylpheed-claws contain a vulnerability that can be
triggered when replying to specially crafted messages.
Background
==========
Sylpheed is a lightweight email client and newsreader. Sylpheed-claws
is a 'bleeding edge' version of Sylpheed.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 mail-client/sylpheed < 1.0.3 >= 1.0.3
2 mail-client/sylpheed-claws < 1.0.3 >= 1.0.3
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
Sylpheed and Sylpheed-claws fail to properly handle non-ASCII
characters in email headers when composing reply messages.
Impact
======
An attacker can send an email containing a malicious non-ASCII header
which, when replied to, would cause the program to crash, potentially
allowing the execution of arbitrary code with the privileges of the
user running the software.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Sylpheed users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/sylpheed-1.0.3"
All Sylpheed-claws users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/sylpheed-claws-1.0.3"
