Description:
Two vulnerabilities have been reported in Apache, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a system, or by malicious, local users to gain escalated privileges.
1) An input validation error within the apr-util library's IPv6 URI parsing functionality can be exploited via a specially crafted request.
Successful exploitation crashes a httpd child process. However, it is reportedly believed that the vulnerability may allow code execution on BSD systems.
The vulnerability affects versions 2.0.35 through 2.0.50.
2) A boundary error within the expansion of environment variables when parsing configuration files can be exploited to cause a buffer overflow via a specially crafted ".htaccess" file.
Successful exploitation may allow a malicious, local user to gain escalated privileges.
The vulnerability affects versions 2.0.35 through 2.0.50.
