Debian - Two Security Advisories:
1. New adzapper packages fix denial of service [DSA 966-1]
2. New elog packages fix arbitrary code execution [DSA 967-1]
Detail
======
Security advisory summaries:
1. Thomas Reifferscheid discovered that adzapper, a proxy advertisement
zapper add-on, when installed as plugin in squid, the Internet object
cache, can consume a lot of CPU resources and hence cause a denial of
service on the proxy host.
2. Several security problems have been found in elog, an electronic logbook
to manage notes.

Package : adzapper
Vulnerability : denial of service
Problem type : remote
Debian-specific: no
CVE ID : CVE-2006-0046
Debian Bug : 350308
Thomas Reifferscheid discovered that adzapper, a proxy advertisement
zapper add-on, when installed as plugin in squid, the Internet object
cache, can consume a lot of CPU resources and hence cause a denial of
service on the proxy host.
The old stable distribution (woody) does not contain an adzapper package.
For the stable distribution (sarge) this problem has been fixed in
version 20050316-1sarge1.
For the unstable distribution (sid) this problem has been fixed in
version 20060115-1.
We recommend that you upgrade your adzapper package.
Upgrade Instructions
- - --------------------
wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
If you are using the apt-get package manager, use the line for
sources.list as given below:
apt-get update
will update the internal database
apt-get upgrade
will install corrected packages
You may use an automated update by adding the resources from the
footer to the proper configuration.

Package : elog
Vulnerability : several
Problem-Type : remote
Debian-specific: no
CVE IDs : CVE-2006-4439 CVE-2006-0347 CVE-2006-0348 CVE-2006-0597
CVE-2006-0598 CVE-2006-0599 CVE-2006-0600
Debian Bug : 349528
Several security problems have been found in elog, an electonic logbook
to manage notes. The Common Vulnerabilities and Exposures Project
identifies the following problems:
CVE-2005-4439
"GroundZero Security" discovered that elog insufficiently checks the
size of a buffer used for processing URL parameters, which might lead
to the execution of arbitrary code.
CVE-2006-0347
It was discovered that elog contains a directory traveral vulnerability
in the processing of "../" sequences in URLs, which might lead to
information disclosure.
CVE-2006-0348
The code to write the log file contained a format string vulnerability,
which might lead to the execution of arbitrary code.
CVE-2006-0597
Overly long revision attributes might trigger a crash due to a buffer
overflow.
CVE-2006-0598
The code to write the log file does not enforce bounds checks properly,
which might lead to the execution of arbitrary code.
CVE-2006-0599
elog emitted different errors messages for invalid passwords and invalid
users, which allows an attacker to probe for valid user names.
CVE-2006-0600
An attacker could be driven into infinite redirection with a crafted
"fail" request, which has denial of service potential.
The old stable distribution (woody) does not contain elog packages.
For the stable distribution (sarge) these problems have been fixed in
version 2.5.7+r1558-4+sarge2.
For the unstable distribution (sid) these problems have been fixed in
version 2.6.1+r1642-1.
We recommend that you upgrade your elog package.
