Background
Apache2 is a widely used open-source web server software. It provides a reliable and efficient platform for serving web content. The Apache HTTP server is a critical component of many web applications and is known for its stability and performance. However, several security vulnerabilities have been discovered in Apache2 that could potentially be exploited by attackers.
Vulnerability Detail
The Apache2 security update addresses multiple vulnerabilities:
-
CVE-2014-0118: The DEFLATE input filter in mod_deflate allows remote attackers to cause a denial of service by sending crafted request data that decompresses to a much larger size, leading to resource consumption.
-
CVE-2014-0226: A race condition in mod_status could allow an attacker to send carefully crafted requests, leading to a heap buffer overflow. This could result in denial of service, disclosure of sensitive information, or even the execution of arbitrary code.
-
CVE-2014-0231: A flaw in mod_cgid could be exploited by a remote attacker to cause child processes to hang indefinitely, resulting in denial of service if the server hosts CGI scripts that do not consume standard input.
