A format string bug exists in the textual web browser W3M.
The bug results in a crash of W3M under run-time options "-dump" or "-backend" if requesting HTTPS URLs and printf(3)
escape sequences like "%n%n" occur in the Common Name (CN) of the website X.509 certificate.
An updated package addresses this issue.

Several remote vulnerabilities have been discovered in elog, a web-based electronic logbook,
which may lead to the execution of arbitrary code.
Gv is the PostScript and PDF viewer for X. It performs insufficient boundary checks in the Postscript parsing code,
which allows the execution of arbitrary code through a buffer overflow.
Evince embeds a copy of gv and needs an update as well.
It was discovered that the Xine multimedia library performs insufficient sanitising of Real streams,
which might lead to the execution of arbitrary code through a buffer overflow.
Updated packages solve these problems.

Cross-site scripting vulnerabilities in the mailto parameter of webmail.php, the session and delete_draft
parameters of compose.php and through a shortcoming in the magicHTML filter have been found.
An attacker could abuse these to execute malicious JavaScript in the user's webmail session.
An updated package addresses this issue.

A buffer overflow was discovered in the "parse_expression" function of the "permissions" module of the SIP router OpenSER,
versions up to and including 1.1.0.
The buffer overflow is triggered by parsing a configuration line expression consisting of more than 500 characters and
potentially could lead to the execution of arbitrary code under the privileges of the OpenSER process.
So it's recommended to update to the latest version.

Certain Sun products (including some bundled third party products) may be vulnerable to an RSA Signature Verification
vulnerability that allows unauthorized forged certificates to be validated.
This may result in a number of different types of remote exploits.
Affected Software is JDK, NSS, OpenSSL bundled with Solaris, Mozilla, IPsec/IKE, Secure Global Desktop, GnuTLS bundled
with Solaris, StarOffice, SJS Server Products, and Solaris WAN Boot.
Updated packages are available now.

Novell NetMail is an e-mail and calendar system that is based on standard Internet protocols.
Remote exploitation of a buffer overflow vulnerability in Novell Inc.'s NetMail IMAP daemon version 3.52
allows authenticated attackers to execute arbitrary code with the privileges of the underlying user.
Once logged in, attackers can execute the "subscribe" command with an overly long argument string to
overflow a stack based buffer.
Novell has addressed this vulnerability in version 3.52e FTF2 of NetMail.

When connecting to a remote DB2 instance, the version 7 client typically sends a SQLJRA packet requesting start
of the connection. If this SQLJRA packet is specially crafted, it can cause a Denial-of-Service attack by crashing the
DB2 instance. This can do any remote unauthenticated attacker.
Fixpack 13 for DB2 version 8.1 has been published to solve this problem.
