Multiple vulnerabilities has been found and corrected in mono:
IOActive Inc. found a buffer overflow in Mono.Math.BigInteger class
in Mono 1.2.5.1 and previous versions, which allows arbitrary code
execution by context-dependent attackers (CVE-2007-5197).
Multiple cross-site scripting (XSS) vulnerabilities in the ASP.net
class libraries in Mono 2.0 and earlier allow remote attackers to
inject arbitrary web script or HTML via crafted attributes related to
(1) HtmlControl.cs (PreProcessRelativeReference), (2) HtmlForm.cs
(RenderAttributes), (3) HtmlInputButton (RenderAttributes),
(4) HtmlInputRadioButton (RenderAttributes), and (5) HtmlSelect
(RenderChildren) (CVE-2008-3422).
CRLF injection vulnerability in Sys.Web in Mono 2.0 and earlier allows
remote attackers to inject arbitrary HTTP headers and conduct HTTP
response splitting attacks via CRLF sequences in the query string
(CVE-2008-3906).
The XML HMAC signature system did not correctly check certain
lengths. If an attacker sent a truncated HMAC, it could bypass
authentication, leading to potential privilege escalation
(CVE-2009-0217).
Packages for 2008.0 are being provided due to extended support for
Corporate products.
The updated packages have been patched to fix these issues.
