    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.
