new xulrunner-1.9.

Original advisory details:

 A flaw was discovered in the browser engine. A variable could be made to
 overflow causing the browser to crash. If a user were tricked into opening
 a malicious web page, an attacker could cause a denial of service or
 possibly execute arbitrary code with the privileges of the user invoking
 the program. (CVE-2008-2785)

 Billy Rios discovered that Firefox and xulrunner, as used by browsers
 such as Epiphany, did not properly perform URI splitting with pipe
 symbols when passed a command-line URI. If Firefox or xulrunner were
 passed a malicious URL, an attacker may be able to execute local
 content with chrome privileges. (CVE-2008-2933)");
