Version Summary:Juniper has released a security bulletin and updated software to address the OpenSSL ssl3_read_bytes remote denial of service vulnerability.
 
 
Description
A vulnerability in OpenSSL version 1.0.0-beta5 could allow an unauthenticated, remote attacker to conduct a denial of service (DoS) condition on a targeted system.

The vulnerability is due to improper memory operations performed by the affected software. An attacker could exploit this vulnerability by submitting crafted data to the targeted system. Processing the data could cause the affected application to crash, resulting in a DoS condition.

OpenSSL has confirmed the vulnerability and released software updates.
 
Warning Indicators
The following OpenSSL versions are vulnerable:

OpenSSL 1.0.0
OpenSSL 1.0.1a
OpenSSL 1.0.1b
OpenSSL 1.0.1c
OpenSSL 1.0.1d
OpenSSL 1.0.1e
OpenSSL 1.0.1f
OpenSSL 1.0.1g

 
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a file or link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the link.

Impact
An attacker could exploit this vulnerability to cause an affected application to crash, resulting in a DoS condition.
 
Technical Information
The vulnerability exists in handling multithreaded SSL connections. The SSL_read() function fails when the SSL_MODE_RELEASE_BUFFERS flag is set, which could lead to a race condition.

An attacker could exploit the vulnerability by transmitting crafted requests into an SSL stream, which could release a buffer even if there is some data in it. When the malicious request is processed, a use-after-free memory pointer error could allow the attacker to execute arbitrary code or cause a DoS condition.
 
Safeguards
Administrators are advised to apply the appropriate updates.

Users are advised not to open files from suspicious or unrecognized sources. If users cannot verify that files are safe, they are advised not to open them.

Administrators are advised to monitor affected systems.
