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.
