ALAS-2014-388


Amazon Linux AMI Security Advisory: ALAS-2014-388
Advisory Release Date: 2014-09-19 11:39 Pacific
Severity: Important

Issue Overview:

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 )
