The Apache Software Foundation and the Apache HTTP Server Project are pleased to announce the release of version 2.2.17 of the Apache HTTP Server ("Apache"). This version of Apache is principally a bug fix release, and a security fix release of the APR-util 1.3.10 dependency; * SECURITY: CVE-2010-1623 (cve.mitre.org) Fix a denial of service attack against apr_brigade_split_line(). * SECURITY: CVE-2009-3560, CVE-2009-3720 (cve.mitre.org) Fix two buffer over-read flaws in the bundled copy of expat which could cause httpd to crash while parsing specially-crafted XML documents. We consider this release to be the best version of Apache available, and encourage users of all prior versions to upgrade. Apache HTTP Server 2.2.17 is available for download from: http://httpd.apache.org/download.cgi Apache HTTP Server 2.0.64 legacy release is also currently available, with the same vulnerability correction as well as many others fixed in 2.2.16 and earlier releases. See the corresponding CHANGES files linked from the download page. The Apache HTTP Project developers strongly encourage all users to migrate to Apache 2.2, as only limited and less frequent maintenance is provided for legacy versions. Apache 2.2 offers numerous enhancements, improvements, and performance boosts over the 2.0 codebase. For an overview of new features introduced since 2.0 please see: http://httpd.apache.org/docs/2.2/new_features_2_2.html Please see the CHANGES_2.2 file, linked from the download page, for a full list of changes. A condensed list, CHANGES_2.2.17 provides the complete list of changes since 2.2.16. A summary of all of the security vulnerabilities addressed in this and earlier releases is available: http://httpd.apache.org/security/vulnerabilities_22.html This release includes the Apache Portable Runtime (APR) version 1.4.2 and APR Utility Library (APR-util) version 1.3.10, bundled with the tar and zip distributions. The APR libraries libapr and libaprutil (and on Win32, libapriconv version 1.2.1) must all be updated to ensure binary compatibility and address many known security and platform bugs. This release builds on and extends the Apache 2.0 API. Modules written for Apache 2.0 will need to be recompiled in order to run with Apache 2.2, and require minimal or no source code changes. http://svn.apache.org/repos/asf/httpd/httpd/branches/2.2.x/VERSIONING When upgrading or installing this version of Apache, please bear in mind that if you intend to use Apache with one of the threaded MPMs (other than the Prefork MPM), you must ensure that any modules you will be using (and the libraries they depend on) are thread-safe.
Multiple race conditions in smtpd.py in the smtpd module in Python 2.6, 2.7, 3.1, and 3.2 alpha allow remote attackers to cause a denial of service (daemon outage) by establishing and then immediately closing a TCP connection, leading to the accept function having an unexpected return value of None, an unexpected value of None for the address, or an ECONNABORTED, EAGAIN, or EWOULDBLOCK error, or the getpeername function having an ENOTCONN error, a related issue to CVE-2010-3492. (CVSS:4.3) (Last Update:2013-05-14)
The asyncore module in Python before 3.2 does not properly handle unsuccessful calls to the accept function, and does not have accompanying documentation describing how daemon applications should handle unsuccessful calls to the accept function, which makes it easier for remote attackers to conduct denial of service attacks that terminate these applications via network connections. (CVSS:5.0) (Last Update:2011-07-18)
Symantec Security Response has created a short video to introduce you to some of the common hiding places for malware. The video presented by Benjamin Nahorney (Senior Information Developer) takes you through the following topics:
1) Looking for suspicious programs in Windows Startup by using msconfig.
2) Checking the list of running processes and services using Windows Task Manager and services.msc tool.
3) Visually checking the System folders for suspect files with Windows Explorer.
4) Submitting the any suspicious files to Symantec security response for analysis using the Web Sample Submission page.
5) Tracking and reviewing the response provided by Symantec to your submission.
