Package        : elog
Vulnerability  : several
Problem-Type   : remote
Debian-specific: no
CVE ID         : CVE-2006-5063 CVE-2006-5790 CVE-2006-5791 CVE-2006-6318

Several remote vulnerabilities have been discovered in elog, a web-based
electronic logbook, which may lead to the execution of arbitrary code.
The Common Vulnerabilities and Exposures project identifies the following


    Tilman Koschnick discovered that log entry editing in HTML is vulnerable
    to cross-site scripting. This update disables the vulnerable code.


    Ulf Harnhammar of the Debian Security Audit Project discovered several
    format string vulnerabilities in elog, which may lead to execution of
    arbitrary code.


    Ulf Harnhammar of the Debian Security Audit Project discovered 
    cross-site scripting vulnerabilities in the creation of new logbook


    Jayesh KS and Arun Kethipelly of OS2A discovered that elog performs
    insufficient error handling in config file parsing, which may lead to
    denial of service through a NULL pointer dereference.

For the stable distribution (sarge) these problems have been fixed in
version 2.5.7+r1558-4+sarge3.

The upcoming stable distribution (etch) will no longer include elog.

For the unstable distribution (sid) these problems have been fixed in
version 2.6.2+r1754-1.

We recommend that you upgrade your elog package.
