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.
