Package : libxml2
CVE ID : CVE-2014-0191 CVE-2014-3660
Debian Bug : 768089

It was discovered that the update released for libxml2 in DSA 2978 fixing
CVE-2014-0191 was incomplete. This caused libxml2 to still fetch external
entities regardless of whether entity substitution or validation is
enabled.

In addition, this update addresses a regression introduced in DSA 3057 by
the patch fixing CVE-2014-3660. This caused libxml2 to not parse an
entity when it's used first in another entity referenced from an
attribute value.

For the stable distribution (wheezy), these problems have been fixed in
version 2.8.0+dfsg1-7+wheezy3.

For the upcoming stable distribution (jessie), these problems have been
fixed in version 2.9.1+dfsg1-4.

For the unstable distribution (sid), these problems have been fixed in
version 2.9.1+dfsg1-4.

We recommend that you upgrade your libxml2 packages.
