CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in OpenSSL (Network Encryption Software) and classified as problematic. Affected by this issue is the function do_ssl3_write of the file ssl/s3_pkt.c of the component SSLv3 Packet Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is availability. CVE summarizes:

The do_ssl3_write function in s3_pkt.c in OpenSSL 1.x through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, does not properly manage a buffer pointer during certain recursive calls, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors that trigger an alert condition.

The issue has been introduced in 03/29/2010. The weakness was released 04/21/2014 by David Ramos as Bug 3321 as confirmed bug report (Bug Tracker). The advisory is shared for download at rt.openssl.org. This vulnerability is handled as CVE-2014-0198 since 12/03/2013. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are known technical details, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 1484 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 74045 (Debian DSA-2931-1 : openssl - security update), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 350258 (Amazon Linux Security Advisory for openssl: AL2012-2014-003).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at anoncvs.estpak.ee. A possible mitigation has been published 5 days after the disclosure of the vulnerability. The vulnerability will be addressed with the following lines of code:

if (wb->buf == NULL)
   if (!ssl3_setup_write_buffer(s))
      return -1;

The vulnerability is also documented in the databases at X-Force (93000), Tenable (74045), SecurityFocus (BID 67193†), OSVDB (106531†) and Secunia (SA58297†). seclists.org is providing further details. Entries connected to this vulnerability are available at VDB-11600, VDB-11705, VDB-11778 and VDB-13014. If you want to get best quality of vulnerability data, you may have to visit VulDB.
