Description

This security bulletin contains information about 1 security vulnerability.


1) Buffer overflow when processing HTTP requests (CVE-ID: CVE-2015-1548)

The vulnerability allows a remote attacker to obtain potentially sensitive information.

The vulnerability exists due to improper handling of long string passed via HTTP request. A remote attacker can send a specially crafted HTTP GET request with protocol name longer than 10000 bytes, cause out-of-bounds read and obtain potentially sensitive information from system memory.

Exploitation example:

perl -e 'print "GET / " . "X"x65536 . "/Y" . "\r\n\r\n"' | ncat localhost 80

Successful exploitation of this vulnerability may allow an attacker to obtain potentially sensitive data stored in RAM, such as passwords, private encryption keys etc.
