- ------------------------------------------------------------------------- Debian Security Advisory DSA-2579-1 security@debian.org http://www.debian.org/security/ Stefan Fritsch November 30, 2012 http://www.debian.org/security/faq - -------------------------------------------------------------------------
Package : apache2 Vulnerability : Multiple issues Problem type : remote Debian-specific: no CVE ID : CVE-2012-4557 CVE-2012-4929 Debian Bug : 689936
A vulnerability has been found in the Apache HTTPD Server:
CVE-2012-4557
A flaw was found when mod_proxy_ajp connects to a backend server that takes too long to respond. Given a specific configuration, a remote attacker could send certain requests, putting a backend server into an error state until the retry timeout expired. This could lead to a temporary denial of service.
In addition, this update also adds a server side mitigation for the following issue:
CVE-2012-4929
If using SSL/TLS data compression with HTTPS in an connection to a web browser, man-in-the-middle attackers may obtain plaintext HTTP headers. This issue is known as the "CRIME" attack. This update of apache2 disables SSL compression by default. A new SSLCompression directive has been backported that may be used to re-enable SSL data compression in environments where the "CRIME" attack is not an issue. For more information, please refer to: http://httpd.apache.org/docs/2.4/mod/mod_ssl.html#sslcompression
For the stable distribution (squeeze), these problems have been fixed in version 2.2.16-6+squeeze10.
For the testing distribution (wheezy), these problems have been fixed in version 2.2.22-12.
For the unstable distribution (sid), these problems have been fixed in version 2.2.22-12.
We recommend that you upgrade your apache2 packages.
