Description

It was discovered that the Mono System.Web library incorrectly filtered certain error messages related to forbidden files. If a user were tricked into opening a specially crafted URL, an attacker could possibly exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2012-3382)

It was discovered that the Mono System.Web library incorrectly handled the EnableViewStateMac property. If a user were tricked into opening a specially crafted URL, an attacker could possibly exploit this to conduct cross-site scripting (XSS) attacks. This issue only affected Ubuntu 10.04 LTS. (CVE-2010-4159).

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.
