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
problems:

CVE-2006-5063

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

CVE-2006-5790

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

CVE-2006-5791

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

CVE-2006-6318

    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.
