EnGarde Secure Linux v1.0.1 - EnGarde is a secure distribution of Linux
engineered from the ground-up to provide organizations with the level of
security required to create a corporate Web presence or even conduct
e-business on the Web. It can be used as a Web, DNS, e-mail, database,

concern.

| xmcd | ----------------------------//
+---------------------------------+
Cda, a setuid commandline part of xmcd, a X11/Motif audio CD player by Ti
Kan , was found vulnerable by a link attack and some bufferoverflows.
These bugs could be exploited by an adversary, who has access to the
system, to overwrite files or gain higher privileges.
SuSE-7.2

+---------------------------------+
| tomcat | ----------------------------//
+---------------------------------+
There are several security problems with Jakarta-Tomcat, a Java
Servlet Engine, shipped as part of OpenLinux 3.1 Server. Several
vulnerabilities allowed attackers to view files in the system. A
second problem allowed so-called cross-site scripting, where a
hostile Web server can feed JavaScript or other code to a web
browser, making it appear to originate from the server running
tomcat.

+---------------------------------+
| squid | ----------------------------//
+---------------------------------+
There is a security problem with Squid, a proxy server shipped as
part of OpenLinux 3.1 Server. If Squid is configured for accelerator
mode (setting http_accel_with_proxy off), any request to Squid is
allowed. Malicious users may use your proxy to portscan remote
systems, forge email, and other activities.

+---------------------------------+
| Zope | ----------------------------//
+---------------------------------+
We *highly* recommend that any Zope site running Zope 2.3.3, Zope
2.4.0 final or any alpha or beta version of 2.4.0 have this hotfix
product installed to mitigate the issue. Zope 2.4.1 will contain a
fix for the issue, at which time the hotfix can be removed.

Vendor Advisory:
http://www.linuxsecurity.com/advisories/other_advisory-1535.html
+---------------------------------+
| FreeBSD | ----------------------------//
+---------------------------------+
A flaw exists in FreeBSD signal handler clearing that would allow for
some signal handlers to remain in effect after the exec. Most of the
signals were cleared, but some signal hanlders were not. This
allowed an attacker to execute arbitrary code in the context of a
setuid binary.

FreeBSD Advisory:

http://www.linuxsecurity.com/advisories/freebsd_advisory-1537.html
+---------------------------------+
| OpenLDAP | ----------------------------//
+---------------------------------+
The problem is that slapd did not handle packets with an invalid BER
length of length fields and would crash if it received those. An
attacked can use this to mount a denial of service attack remotely.

+---------------------------------+
| xloadimage | ----------------------------//
+---------------------------------+
The version of xloadimage (a graphics files viewer for X) that was
shipped in Debian GNU/Linux 2.2 has a buffer overflow in the code
that handles FACES format images. This could be exploited by an
attacker by tricking someone into viewing a specially crafted image
using xloadimage which would allow him to execute arbitrary code.

+---------------------------------+
| Kerberos | ----------------------------//
+---------------------------------+
Updated Kerberos 5 packages are now available for Red Hat Linux 6.2,
7, and 7.1. These updates close vulnerabilities due to potential
buffer overflows in the Kerberos-aware telnet server included in the
krb5-workstation package.

+---------------------------------+
| openLDAP | ----------------------------//
+---------------------------------+
When subjected to the PROTOS LDAPv3 test suite, versions of OpenLDAP
1.2 through 1.2.11 and 2.0 through 2.0.7 were found to have
vulnerabilities which could be exploited by causing them to attempt
to decode an improperly encoded request. These vulnerabilities were
fixed in OpenLDAP 1.2.12 and 2.0.8.
