Scientific Linux: 2014-0920-1 Important Httpd Denial of Service

Important: httpd security update. Date: Wed, 23 Jul 2014 13:43:11 +0000 Reply-To: scientific-linux-users@ Sender: Security Errata for Scientific Linux From: Pat Riehecky Subject: Security ERRATA Important: httpd on SL5.x, SL6.x i386/x86_64 MIME-Version: 1.0 Synopsis: Important: httpd security update Advisory ID: SLSA-2014:0920-1 Issue Date: 2014-07-23 CVE Numbers: CVE-2014-0231 CVE-2014-0118 CVE-2014-0226 -- A race condition flaw, leading to heap-based buffer overflows, was found in the mod_status httpd module. A remote attacker able to access a status page served by mod_status on a server using a threaded Multi-Processing Module (MPM) could send a specially crafted request that would cause the httpd child process to crash or, possibly, allow the attacker to execute arbitrary code with the privileges of the "apache" user. (CVE-2014-0226) A denial of service flaw was found in the way httpd's mod_deflate module handled request body decompression (configured via the "DEFLATE" input filter). A remote attacker able to send a request whose body would be decompressed could use this flaw to consume an excessive amount of system memory and CPU on the target system. (CVE-2014-0118) A denial of service flaw was found in the way httpd's mod_cgid module executed CGI scripts that did not read data from the standard input. A remote attacker could submit a specially crafted request that would cause the httpd child process to hang indefinitely. (CVE-2014-0231) After installing the updated packages, the httpd daemon will be restarted automatically. -- SL5 x86_64 httpd-2.2.3-87.sl5.x86_64.rpm httpd-debuginfo-2.2.3-87.sl5.x86_64.rpm mod_ssl-2.2.3-87.sl5.x86_64.rpm httpd-debuginfo-2.2.3-87.sl5.i386.rpm httpd-devel-2.2.3-87.sl5.i386.rpm httpd-devel-2.2.3-87.sl5.x86_64.rpm httpd-manual-2.2.3-87.sl5.x86_64.rpm i386 httpd-2.2.3-87.sl5.i386.rpm httpd-debuginfo-2.2.3-87.sl5.i386.rpm mod_ssl-2.2.3-87.sl5.i386.rpm httpd-devel-2.2.3-87.sl5.i386.rpm httpd-manual-2.2.3-87.sl5.i386.rpm SL6 x86_64 httpd-2.2.15-31.sl6.x86_64.rpm httpd-debuginfo-2.2.15-31.sl6.x86_64.rpm httpd-tools-2.2.15-31.sl6.x86_64.rpm httpd-debuginfo-2.2.15-31.sl6.i686.rpm httpd-devel-2.2.15-31.sl6.i686.rpm httpd-devel-2.2.15-31.sl6.x86_64.rpm mod_ssl-2.2.15-31.sl6.x86_64.rpm i386 httpd-2.2.15-31.sl6.i686.rpm httpd-debuginfo-2.2.15-31.sl6.i686.rpm httpd-tools-2.2.15-31.sl6.i686.rpm httpd-devel-2.2.15-31.sl6.i686.rpm mod_ssl-2.2.15-31.sl6.i686.rpm noarch httpd-manual-2.2.15-31.sl6.noarch.rpm - Scientific Linux Development Team .
