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:


    "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.


    It was discovered that elog contains a directory traveral vulnerability
    in the processing of "../" sequences in URLs, which might lead to
    information disclosure.


    The code to write the log file contained a format string vulnerability,
    which might lead to the execution of arbitrary code.


    Overly long revision attributes might trigger a crash due to a buffer


    The code to write the log file does not enforce bounds checks properly,
    which might lead to the execution of arbitrary code.


    elog emitted different errors messages for invalid passwords and invalid
    users, which allows an attacker to probe for valid user names.


    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.

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.
