Package : xterm
Version : 327-2+deb9u2
Debian Bug : 984615
DLA 2558-2 backported a part of the upstream patch which fails
to deal with the realloc failures in Debian stretch. This update
reverts that part of the patch since it's not really needed and
just focuses on fixing CVE-2021-27135.
For Debian 9 stretch, this problem has been fixed in version
327-2+deb9u2.
We recommend that you upgrade your xterm packages.
