TITLE:
Apple Safari WebKit "servePendingRequests()" Use-After-Free Weakness

SECUNIA ADVISORY ID:
SA33495

VERIFY ADVISORY:
http://secunia.com/advisories/33495/

DESCRIPTION:
A weakness has been discovered in Apple Safari, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The weakness is caused due to a use-after-free error while calling
the "servePendingRequests()" function in WebKit. This can be
exploited to dereference invalid memory and cause a crash when a user
visits a specially crafted web page.

Successful exploitation crashes the browser. However, even though
code execution has not been proven, it cannot be completely ruled
out.

NOTE: Secunia normally does not classify a browser crash as a
vulnerability nor issue an advisory about it. However, the potential
impact of this issue may be more severe than currently believed.

The weakness is confirmed in Apple Safari version 4.0 (530.17) for
Windows. Other versions may also be affected.

SOLUTION:
Fixed in the WebKit development repository.
http://trac.webkit.org/changeset/44519

Do not browse untrusted websites or follow untrusted links.
