Description:
Two vulnerabilities have been reported in Apache, which can be exploited by malicious people to cause a DoS (Denial of Service).
1) An error exists in mod_proxy_ftp when processing responses received from FTP servers. This can be exploited to trigger a NULL-pointer dereference and crash an Apache child process via a malformed EPSV response.
Successful exploitation requires that a threaded Multi-Processing Module is used and that the mod_proxy_ftp module is enabled.
The vulnerability is confirmed in Apache versions 2.0.63 and 2.2.13. Other versions may also be affected.
2) An error in the included APR-util library can be exploited to trigger hangs in the prefork and event MPMs on Solaris.
For more information see vulnerability #2 in:
SA36138
The vulnerability is reported in 2.2.x versions prior to 2.2.14.
