CVE Reference(s):

Description


A vulnerability and a security issue have been discovered in Apple Safari, which may lead to exposure of sensitive information or can be exploited by malicious people to compromise a user's system.

1) A use-after-free error when handling pop-up boxes created from a child window can be exploited to execute arbitrary code when a user visits a specially crafted web page.

2) Safari includes HTTP basic authentication credentials in an HTTP request if a web page that requires HTTP basic authentication redirects to a different domain (e.g. via a "Location" header).

The vulnerability and the security issue are confirmed in version 4.0.5 for Windows. Other versions may also be affected.


Solution:
Upgrade to version 5.0, which fixes vulnerability #1. Do not authenticate to sites that use HTTP basic authentication and use redirections to different domains.

Provided and/or discovered by:
1) Krystian Kloskowski (h07)
2) Vin Lisciandro
