Package : libxml2
Version : 2.9.4+dfsg1-2.2+deb9u7
CVE ID : CVE-2022-29824
Debian Bug : 1010526

Felix Wilhelm discovered that libxml2, the GNOME XML library, did not correctly
check for integer overflows or used wrong types for buffer sizes. This could
result in out-of-bounds writes or other memory errors when working on large,
multi-gigabyte buffers.

For Debian 9 stretch, this problem has been fixed in version
2.9.4+dfsg1-2.2+deb9u7.

We recommend that you upgrade your libxml2 packages.
