Jueri Aedla discovered a buffer overflow in the libxml XML library, which
could result in the execution of arbitrary code.
For the stable distribution (squeeze), this problem has been fixed in
version 2.7.8.dfsg-2+squeeze6.
For the unstable distribution (sid), this problem has been fixed in
version 2.8.0+dfsg1-7.
We recommend that you upgrade your libxml2 packages.
