Ubuntu 4.10 / 5.04 / 5.10 : apache2, apache vulnerabilities (USN-241-1)

Medium Nessus Plugin ID 20788


The remote Ubuntu host is missing one or more security-related patches.


The 'mod_imap' module (which provides support for image maps) did not properly escape the 'referer' URL which rendered it vulnerable against a cross-site scripting attack. A malicious web page (or HTML email) could trick a user into visiting a site running the vulnerable mod_imap, and employ cross-site-scripting techniques to gather sensitive user information from that site. (CVE-2005-3352)

Hartmut Keil discovered a Denial of Service vulnerability in the SSL module ('mod_ssl') that affects SSL-enabled virtual hosts with a customized error page for error 400. By sending a specially crafted request to the server, a remote attacker could crash the server. This only affects Apache 2, and only if the 'worker' implementation (apache2-mpm-worker) is used. (CVE-2005-3357).

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.


Update the affected packages.
