New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Debian host is missing a security update.
DescriptionSeveral vulnerabilities have been found in the Apache HTTPD server.
Emmanuel Dreyfus reported that the use of ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed.
Vasileios Panopoulos of AdNovum Informatik AG discovered that mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port leading to a denial of service.
Javier Jimenez reported that the HTTP strict parsing contains a flaw leading to a buffer overread in ap_find_token(). A remote attacker can take advantage of this flaw by carefully crafting a sequence of request headers to cause a segmentation fault, or to force ap_find_token() to return an incorrect value.
ChenQin and Hanno Boeck reported that mod_mime can read one byte past the end of a buffer when sending a malicious Content-Type response header.
For Debian 7 'Wheezy', these problems have been fixed in version 2.2.22-13+deb7u9.
We recommend that you upgrade your apache2 packages.
