CVE-2008-4225

Drew Yao discovered that missing input sanitising in the xmlBufferResize() function may lead to an infinite loop, resulting in denial of service.

CVE-2008-4226

Drew Yao discovered that an integer overflow in the xmlSAX2Characters() function may lead to denial of service or the execution of arbitrary code.

For the stable distribution (etch), these problems have been fixed in version 2.6.27.dfsg-6.

For the upcoming stable distribution (lenny) and the unstable distribution (sid), these problems have been fixed in version 2.6.32.dfsg-5.

We recommend that you upgrade your libxml2 packages.");
