PROBLEM:
Two vulnerabilities have been reported in Apache HTTP Server, which can be exploited by malicious people to disclose potentially sensitive information and compromise a vulnerable system.

PLATFORM:
Apache 2.0.x
Apache HTTP Server 2.x

ABSTRACT:
Two vulnerabilities have been reported in Apache HTTP Server

REFERENCE LINKS:
CVE-2012-0053
CVE-2013-1862
http://secunia.com/advisories/54320/

IMPACT ASSESSMENT:
Medium

DISCUSSION:
protocol.c in the Apache HTTP Server 2.2.x through 2.2.21 does not properly restrict header information during construction of Bad Request (aka 400) error documents, which allows remote attackers to obtain the values of HTTPOnly cookies via vectors involving a (1) long or (2) malformed header in conjunction with crafted web script. 

IMPACT:
Exposure of sensitive information, System access

SOLUTION:
Update to version 2.0.65.
