Synopsis
========
A flaw in Tor may allow the disclosure of arbitrary memory portions.
Background
==========
Tor is an implementation of second generation Onion Routing, a
connection-oriented anonymizing communication service.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/tor < 0.0.9.10 >= 0.0.9.10
Description
===========
A bug in Tor allows attackers to view arbitrary memory contents from an
exit server's process space.
Impact
======
A remote attacker could exploit the memory disclosure to gain sensitive
information and possibly even private keys.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Tor users should upgrade to the latest available version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/tor-0.0.9.10"

Title: SquirrelMail: Several XSS vulnerabilities
Date: June 21, 2005
Bugs: #95937
ID: 200506-19
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Squirrelmail is vulnerable to several cross-site scripting
vulnerabilities which could lead to a compromise of webmail accounts.
Background
==========
SquirrelMail is a webmail package written in PHP. It supports IMAP and
SMTP protocols.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 mail-client/squirrelmail < 1.4.4 >= 1.4.4
< 1.4.0
Description
===========
SquirrelMail is vulnerable to several cross-site scripting issues, most
reported by Martijn Brinkers.
Impact
======
By enticing a user to read a specially-crafted e-mail or using a
manipulated URL, an attacker can execute arbitrary scripts running in
the context of the victim's browser. This could lead to a compromise of
the user's webmail account, cookie theft, etc.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All SquirrelMail users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/squirrelmail-1.4.4"
Note: Users with the vhosts USE flag set should manually use
webapp-config to finalize the update.
