A flaw in the Apache mod_proxy module was found that could potentially lead to a denial of service is using a threaded Multi-Processing Module. On sites where a reverse proxy is configured, a remote attacker could send a special reequest that would cause the Apache child process handling the request to crash. Likewise, a similar crash could occur on sites with a forward proxy configured if a user could be persuaded to visit a malicious site using the proxy (CVE-2007-3847).

A flaw in the Apache mod_autoindex module was found. On sites where directory listings are used and the AddDefaultCharset directive was removed from the configuration, a cross-site-scripting attack could be possible against browsers that to not correctly derive the response character set according to the rules in RGC 2616 (CVE-2007-4465).

The updated packages have been patched to correct this issue.

The remote host is running a version of Mac OS X 10.4 that does not have the security update 2008-003 applied. 

This update contains security fixes for a number of programs.

It was discovered that Apache did not sanitize the Expect header from an HTTP request when it is reflected back in an error message, which could result in browsers becoming vulnerable to cross-site scripting attacks when processing the output. With cross-site scripting vulnerabilities, if a user were tricked into viewing server output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal confidential data (such as passwords), within the same domain. This was only vulnerable in Ubuntu 6.06. (CVE-2006-3918)

It was discovered that when configured as a proxy server and using a threaded MPM, Apache did not properly sanitize its input. A remote attacker could send Apache crafted date headers and cause a denial of service via application crash. By default, mod_proxy is disabled in Ubuntu. (CVE-2007-3847)

It was discovered that mod_autoindex did not force a character set, which could result in browsers becoming vulnerable to cross-site scripting attacks when processing the output. (CVE-2007-4465)

It was discovered that mod_imap/mod_imagemap did not force a character set, which could result in browsers becoming vulnerable to cross-site scripting attacks when processing the output. By default, mod_imap/mod_imagemap is disabled in Ubuntu. (CVE-2007-5000)

It was discovered that mod_status when status pages were available, allowed for cross-site scripting attacks. By default, mod_status is disabled in Ubuntu. (CVE-2007-6388)

It was discovered that mod_proxy_balancer did not sanitize its input, which could result in browsers becoming vulnerable to cross-site scripting attacks when processing the output. By default, mod_proxy_balancer is disabled in Ubuntu. This was only vulnerable in Ubuntu 7.04 and 7.10. (CVE-2007-6421)

It was discovered that mod_proxy_balancer could be made to dereference a NULL pointer. A remote attacker could send a crafted request and cause a denial of service via application crash. By default, mod_proxy_balancer is disabled in Ubuntu. This was only vulnerable in Ubuntu 7.04 and 7.10. (CVE-2007-6422)

It was discovered that mod_proxy_ftp did not force a character set, which could result in browsers becoming vulnerable to cross-site scripting attacks when processing the output. By default, mod_proxy_ftp is disabled in Ubuntu. (CVE-2008-0005).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
