Version        : 3.7.1-1+deb9u3
CVE ID         : CVE-2020-27783

The fix for CVE-2020-27783, released as DLA 2467-1, was incomplete as
the <math/svg> component was still affected by the vulnerability.  This
update includes an additional patch that completes the fix.  Note that a
package with version 3.7.1-1+deb9u2 was uploaded, but before the
publication of the advisory a regression was discovered, which was
immediately corrected prior to publication of this advisory.

For Debian 9 stretch, this problem has been fixed in version

We recommend that you upgrade your lxml packages.
