Description:
Jayesh KS and Arun Kethipelly have discovered a vulnerability in ELOG, which can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to a NULL pointer dereference error when handling an URL with the logbook set to "global" (e.g. "http://[host]:8080/global/").

Successful exploitation crashes the elogd daemon, but requires valid user credentials when a read password is globally configured.

The vulnerability is confirmed in version 2.6.2-1. Other versions may also be affected.

Solution:
Update to version 2.6.2-7.

Provided and/or discovered by:
