Package        : zlib
CVE ID         : CVE-2018-25032
Debian Bug     : 1008265

Danilo Ramos discovered that incorrect memory handling in zlib's deflate
handling could result in denial of service or potentially the execution
of arbitrary code if specially crafted input is processed.

For the oldstable distribution (buster), this problem has been fixed
in version 1:1.2.11.dfsg-1+deb10u1.

For the stable distribution (bullseye), this problem has been fixed in
version 1:1.2.11.dfsg-2+deb11u1.

We recommend that you upgrade your zlib packages.

tracker page at:
