Summary

IBM Tealeaf Customer Experience may be affected by a vulnerability in the 
Apache HTTP server, caused by an error in the mod_status module.

Vulnerability Details

CVEID: CVE-2014-0226

DESCRIPTION:

IBM Tealeaf Customer Experiences PCA uses the Apache HTTP server to render its
web console. Apache HTTP Server is vulnerable to a heap-based buffer overflow,
caused by a race condition in the mod_status module when handling the 
scoreboard. By sending a specially-crafted request, a remote attacker could 
overflow a buffer and execute arbitrary code on the system or cause the 
application to crash.

CVSS Base Score: 7.5

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/94678 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)
