Title
=====
Two Gentoo Linux Security Advisories:
1. GLSA 200511-12 - Scorched 3D: Multiple vulnerabilities
2. GLSA 200511-13 - Sylpheed, Sylpheed-Claws: Buffer overflow in LDIF importer
Detail
======
1. Luigi Auriemma discovered multiple flaws in the Scorched 3D game
server, including a format string vulnerability and several buffer
overflows.
2. Colin Leroy reported buffer overflow vulnerabilities in Sylpheed and
Sylpheed-Claws. The LDIF importer uses a fixed length buffer to store
data of variable length. Two similar problems exist also in the Mutt
and Pine addressbook importers of Sylpheed-Claws.

Title: Scorched 3D: Multiple vulnerabilities
Date: November 15, 2005
Bugs: #111421
ID: 200511-12
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Multiple vulnerabilities in Scorched 3D allow a remote attacker to deny
service or execute arbitrary code on game servers.
Background
==========
Scorched 3D is a clone of the classic "Scorched Earth" DOS game, adding
features like a 3D island environment and Internet multiplayer
capabilities.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 games-strategy/scorched3d <= 39.1 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.
Description
===========
Luigi Auriemma discovered multiple flaws in the Scorched 3D game
server, including a format string vulnerability and several buffer
overflows.
Impact
======
A remote attacker can exploit these vulnerabilities to crash a game
server or execute arbitrary code with the rights of the game server
user. Users not running a Scorched 3D game server are not affected by
these flaws.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
The Scorched 3D package has been hard-masked until a new version
correcting these flaws is released. In the meantime, current users are
advised to unmerge the package:
# emerge --unmerge games-strategy/scorched3d

Title: Sylpheed, Sylpheed-Claws: Buffer overflow in LDIF importer
Date: November 15, 2005
Bugs: #111853
ID: 200511-13
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Sylpheed and Sylpheed-Claws contain a buffer overflow vulnerability
which may lead to the execution of arbitrary code.
Background
==========
Sylpheed is a lightweight email client and newsreader. Sylpheed-Claws
is a 'bleeding edge' version of Sylpheed. They both support the import
of address books in LDIF (Lightweight Directory Interchange Format).
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 mail-client/sylpheed < 2.0.4 >= 2.0.4
2 mail-client/sylpheed-claws < 1.0.5-r1 >= 1.0.5-r1
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
Colin Leroy reported buffer overflow vulnerabilities in Sylpheed and
Sylpheed-Claws. The LDIF importer uses a fixed length buffer to store
data of variable length. Two similar problems exist also in the Mutt
and Pine addressbook importers of Sylpheed-Claws.
Impact
======
By convincing a user to import a specially-crafted LDIF file into the
address book, a remote attacker could 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-2.0.4"
All Sylpheed-Claws users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose
">=mail-client/sylpheed-claws-1.0.5-r1"
