Hello,

A buffer overflow has been found[1] in libxml2 <= 2.9.2, allowing at least denial of service. A patch[2] is available upstream but no new version has been released yet, so we probably should backport it.

There is no CVE assigned[3] yet that I am aware of, I will update as soon as one has been.

Looks like there are two separates issues, CVE-2015-8241 and CVE-2015-8242. I don't see a fix for the second one.

libxml2 2.9.3 has been released, fixing a huge number of security issues:
