Ubuntu 4.10 / 5.04 / 5.10 : apache2, apache vulnerabilities (USN-241-1)
Medium Nessus Plugin ID 20788
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionThe '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).
