ZoneAlarm Pro Firewall gives you full control over your firewall, enabling you to configure it to your security needs by classifying your network settings. It targets and defeats new and advanced attacks that other firewalls miss, giving you maximum security against zero-day attacks.
Updates (3 hours after posting):According to this blog post (see translation),JDK versions greater than 6u211, 7u201, 8u191, and 11.0.1 are not affected by the LDAP attack vector. In these versionscom.sun.jndi.ldap.object.trustURLCodebase is set to false meaning JNDI cannot load remote code using LDAP, except in veryspecific cases.However, there are other attack vectors targeting this vulnerability which can result in RCE. An attacker could still leverageexisting code on the server to execute a payload. An attack targeting the classorg.apache.naming.factory.BeanFactory, present on Apache Tomcat servers, is discussedin this blog post. Also, there are some specific configurations wherea remote JNDI fetch could still take place, as described in this post.Please update to the latest version of log4j for a more complete solution.
In Apache Log4j2 versions up to and including 2.14.1 (excluding security releases 2.3.1, 2.12.2 and 2.12.3),the JNDI features used in configurations, log messages, and parameters do notprotect against attacker-controlled LDAP and other JNDI related endpoints.An attacker who can control log messages or log message parameters can executearbitrary code loaded from LDAP servers when message lookup substitution is enabled.
Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.54 and prior versions.
Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.53 and prior versions.
A bug exists in the way mod_ssl handled client renegotiations. A remote attacker could send a carefully crafted request that would cause mod_ssl to enter a loop leading to a denial of service. This bug can be only triggered with Apache HTTP Server version 2.4.37 when using OpenSSL version 1.1.1 or later, due to an interaction in changes to handling of renegotiation attempts.
An out-of-bounds memory read was found in mod_proxy_fcgi. A malicious FastCGI server could send a carefully crafted response which could lead to a crash when reading past the end of a heap memory or stack buffer. This issue affects version 2.4.10 only.
A flaw was found in mod_proxy in httpd versions 2.4.6 to 2.4.9. A remote attacker could send a carefully crafted request to a server configured as a reverse proxy, and cause the child process to crash. This could lead to a denial of service against a threaded MPM.
A race condition was found in mod_status. An attacker able to access a public server status page on a server using a threaded MPM could send a carefully crafted request which could lead to a heap buffer overflow. Note that it is not a default or recommended configuration to have a public accessible server status page.
A flaw was found in the WinNT MPM in httpd versions 2.4.1 to 2.4.9, when using the default AcceptFilter for that platform. A remote attacker could send carefully crafted requests that would leak memory and eventually lead to a denial of service against the server.
If you want source code, download a current version from the ISC website or our FTP site. Or, install our updated ISC packages for Ubuntu, CentOS/Fedora, and the standard Debian package. If you prefer Docker, get our official Docker image.
We support three major branches of BIND 9 at a time: Stable, Extended-Support, and Development. See this advice: Which version of BIND do I want to download and install? as well as our list of supported platforms.We also maintain a significant feature matrix and changes file. If you would prefer a GUI management interface, you might consider a Commercial Product based on BIND.
Victims are lured into visiting a reasonably popular website within the Alexa top ~100K ranking, where the attackers plant an iframe that sends users through a series of redirections to trigger the malicious download.
For instance, the logs recorded that the attackers installed various commercial remote-access tools on accessible servers and desktops. They appeared to prefer the IT management tool ScreenConnect, but later switched to AnyDesk in an attempt to evade our countermeasures. We also found download logs of various RDP scanning, exploit, and brute-force password tools, and records of successful uses of those tools, so Windows remote desktop was on the menu, too.
In some cases, following the search results for these tools led the attackers into a variety of shady download sites. The advertising networks whose banner ads appear on these sites appear to have generated popup ads that delivered a potentially unwanted app download as the attackers clumsily pulled together a selection of attack tools, further muddying the picture and leaving the server infected with adware, and the browser history cluttered with redirects.
Some of the evidence shows the attacker either inadvertently clicked one of these fake-download-button ads, or suffered from popup or popunder advertisements that pushed unwanted downloads at the attacker, who then installed the adware, perhaps thinking it was the real pirated copy of a hack tool they thought they were downloading. These unintentional self-infections created additional noise in the logs.
In February 2005, an attack by Xiaoyun Wang, Yiqun Lisa Yin, and Hongbo Yu was announced. The attacks can find collisions in the full version of SHA-1, requiring fewer than 269 operations. (A brute-force search would require 280 operations.)
One attack against SHA-1 was Marc Stevens with an estimated cost of $2.77M(2012) to break a single hash value by renting CPU power from cloud servers. Stevens developed this attack in a project called HashClash, implementing a differential path attack. On 8 November 2010, he claimed he had a fully working near-collision attack against full SHA-1 working with an estimated complexity equivalent to 257.5 SHA-1 compressions. He estimated this attack could be extended to a full collision with a complexity around 261. 2b1af7f3a8
